본 발명은 마이컴에 의한 전기분해장치용 SMPS의 제어방법에 관한 것으로서, 더 자세하게는 과전류를 방지하는 동시에 최적의 전기분해 조건을 유지할 수 있도록 마이컴에 의하여 전기분해장치용 SMPS를 제어하는 방법에 관한 것이다.The present invention relates to a method for controlling an electrolysis device SMPS by a microcomputer, and more particularly, to a method for controlling an electrolysis device SMPS by a microcomputer to prevent an overcurrent and maintain optimal electrolysis conditions. .

SMPS(Switching Mode Power Supply)란 반도체 소자의 스위칭 프로세서를 이용하여 전력의 흐름을 제어하는 방식을 말하는 것으로 전자 계산기, 전자 교환기 및 OA 기기 등 전자·통신 기기의 직류 안정화 전원으로서 폭 넓게 이용되고 있다.Switching Mode Power Supply (SMPS) refers to a method of controlling the flow of power using a switching processor of a semiconductor device, and is widely used as a DC stabilized power supply for electronic and communication devices such as electronic calculators, electronic exchangers, and OA devices.

Since the decomposition is completely stopped, there is a problem that the efficiency of electrolysis is reduced.

또한, 종래의 SMPS는 하드웨어적으로 제어되기 때문에 사용자가 원하는 방식으로 SMPS의 동작을 제어할 수 없어, 예를 들어 촉매의 농도에 따라 전기분해장치에 인가되는 전류를 변화시키는 등 전기분해의 다양한 작업조건에 대응한 처리를 수행할 수 없다는 문제점이 있었다.In addition, since the conventional SMPS is hardware-controlled, the user cannot control the operation of the SMPS in a desired manner. For example, various operations of electrolysis such as changing the current applied to the electrolysis device according to the concentration of the catalyst are possible. There was a problem that the processing corresponding to the condition could not be performed.

본 발명은 상기 문제점을 해결하기 위한 것으로, 본 발명의 목적은 전기분해장치에 과전류가 흐르는 것을 방지하는 동시에 연속적으로 전기분해가 이루어지도록 할 수 있는 마이컴에 의한 전기분해장치용 SMPS의 제어방법을 제공하는 것이다.The present invention is to solve the above problems, an object of the present invention is to provide a control method of the SMPS for electrolysis device by the microcomputer to prevent the overcurrent flow to the electrolysis device and to be continuously electrolysis. It is.

이하, 첨부한 도면을 참조하여 본 발명을 보다 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described the present invention in more detail.

도 1은 본 발명을 실시하기 위한 전기분해장치용 SMPS의 블럭도이다.1 is a block diagram of an SMPS for an electrolysis device for practicing the present invention.

본 발명을 실시하기 위한 전기분해장치용 SMPS(10)는 1차측 정류부(1), 스위칭부(2), 트랜스부(3), 2차측 정류부(4), 하한전류 감지센서(5A), 상한전류 감지센서(5B), 마이컴(6), 버스트부(7), 표시부(8), 및 PWM제어부(9)를 포함한다.SMPS (10) for the electrolysis device for carrying out the present invention is the primary rectifier (1), switching unit (2), transformer unit (3), secondary rectifier (4), lower limit current sensor (5A), upper limit And a current sensing sensor 5B, a microcomputer 6, a burst section 7, a display section 8, and a PWM control section 9.

상기 1차측 정류부(1)는 입력된 AC전압을 브리지 정류회로를 이용하여 1차 DC전압으로 정류하고, 상기 트랜스부(3)는 상기 1차측 정류부(1)에 의해서 정류된 1차 DC전압을 1차 권선으로부터 2차 권선으로 전달하며, 상기 2차측 정류부(4)는 상기 트랜스부(3)로부터 수신된 1차 DC전압을 2차 DC전압으로 정류하여 전기분해장치에 안정된 DC전압을 공급한다.The primary side rectifier 1 rectifies the input AC voltage into a primary DC voltage using a bridge rectifier circuit, and the transformer unit 3 rectifies the primary DC voltage rectified by the primary side rectifier 1. The secondary winding is transferred from the primary winding to the secondary winding, and the secondary rectifier 4 rectifies the primary DC voltage received from the transformer 3 into the secondary DC voltage to supply a stable DC voltage to the electrolysis device. .

상기 하한전류 감지센서(5A)는 상기 2차측 정류부(4)로부터 피드백된 출력전류(I)가 하한전류값 이하인지 검출하여 이를 마이컴(6)으로 전달하며, 상기 상한전류 감지센서(5B)는 상기 2차측 정류부(4)로부터 피드백된 출력전류(I)가 상한전류값 이상인지 검출하여 이를 마이컴(6)으로 전달한다.The lower limit current sensor 5A detects whether the output current I fed back from the secondary rectifier 4 is equal to or lower than the lower limit current value, and transmits the same to the microcomputer 6, and the upper limit current sensor 5B It detects whether the output current I fed back from the secondary rectifier 4 is greater than or equal to the upper limit current value and transfers it to the microcomputer 6.

상기 마이컴(6)은 상기 하한전류 감지센서(5A)로부터 하한전류 감지신호가 입력되면 표시부(8)에 최소전류상태 메세지를 출력하고, 상기 상한전류 감지센서(5B)로부터 상한전류 감지신호가 입력되면 표시부(8)에 과전류상태 메세지를 출력한 후 PWM제어부(9)로 전류제어명령을 출력한다.The microcomputer 6 outputs a minimum current status message to the display unit 8 when a lower limit current detection signal is input from the lower limit current detection sensor 5A, and an upper limit current detection signal is input from the upper limit current detection sensor 5B. When the overcurrent status message is output to the display unit 8, the current control command is output to the PWM control unit 9.

상기 버스트부(7)는 상기 마이컴(6)의 제어에 따라 예를 들면 100ms 간격으로 불연속적인 소정의 DC전압을 상기 트랜스부(3)에 공급한다.The burst unit 7 supplies the transformer unit 3 with a predetermined DC voltage discontinuous at intervals of 100 ms, for example, under the control of the microcomputer 6.

상기 표시부(8)는 상기 마이컴(6)으로부터의 상태메세지를 화면에 표시하며, 상기 PWM제어부(9)는 상기 마이컴(6)으로부터의 전류제어명령에 따라 펄스폭을 변화시켜 스위칭부(2)를 통하여 출력전류(I)를 제어한다.The display unit 8 displays a status message from the microcomputer 6 on the screen, and the PWM controller 9 changes the pulse width according to the current control command from the microcomputer 6 to switch the unit 2. Control the output current (I) through.

다음으로 본 발명에 따른 마이컴에 의한 전기분해장치용 SMPS의 제어방법에대하여 도 2를 참조하여 설명한다.Next, a control method of the SMPS for electrolysis device by the microcomputer according to the present invention will be described with reference to FIG.

우선, 마이컴(6)이 상기 버스트부(7)로 버스트모드 명령을 전송하면, 상기 버스트부(7)가 버스트모드 명령에 따라 소정의 버스트모드 설정시간 동안 소정의 DC전압을 트랜스부(3)에 인가하여 전기분해장치용 SMPS를 버스트모드로 작동시킨다(S10~S20).First, when the microcomputer 6 transmits a burst mode command to the burst unit 7, the burst unit 7 transmits a predetermined DC voltage for a predetermined burst mode setting time according to the burst mode command. It is applied to operate the SMPS for electrolysis device in burst mode (S10 ~ S20).

상기 마이컴(6)이 상기 소정의 버스트모드 설정시간이 경과되었는지를 체크하여 소정의 버스트모드 설정시간이 경과되었으면 입력된 AC전압을 DC전압으로 변환하여 전기분해장치용 SMPS를 정상모드로 작동시킨다(S30~S40).The microcomputer 6 checks whether the predetermined burst mode setting time has elapsed, and when the predetermined burst mode setting time has elapsed, converts the input AC voltage into a DC voltage to operate the SMPS for the electrolysis device in the normal mode ( S30 ~ S40).

따라서, 촉매의 농도가 높아 상대적으로 과전류가 발생될 확률이 높은 전기분해 초기시에는 상기 버스트모드에 의하여 전기분해장치에 DC전압을 불연속적으로 공급하므로, 전기분해장치에 연속적으로 DC전압을 인가하는 종래의 SMPS에 비하여 상대적으로 과전류가 흐르는 것을 방지할 수 있다.Therefore, at the initial stage of electrolysis where the catalyst concentration is high and relatively overcurrent is likely to occur, the DC voltage is discontinuously supplied to the electrolysis device by the burst mode, thereby continuously applying the DC voltage to the electrolysis device. It is possible to prevent the overcurrent flowing relative to the conventional SMPS.

또한, 상기 버스트부(7)에 의하여 소정의 DC전압이 전기분해장치에 불연속적으로 인가되어도 전기분해에 의하여 전기분해장치에 전류가 계속 흐르기 때문에 연속적으로 DC전압을 인가하는 방식에 비하여 소비전력을 감소시킬 수 있으며, 전기분해를 천천히 수행하고자 할 때 또는 소량의 전기분해시 매우 유용하다.In addition, even when a predetermined DC voltage is discontinuously applied to the electrolysis device by the burst unit 7, current continues to flow to the electrolysis device by electrolysis. It can be reduced and is very useful when it is desired to carry out electrolysis slowly or in small amounts of electrolysis.

그 다음, 상기 마이컴(6)이 정상모드에서 하한전류 감지센서(5A) 및 상한전류 감지센서(5B)로부터 감지신호가 입력되었는지를 체크하여(S50), 상기 상한전류 감지센서(5B)로부터 감지신호가 입력된 경우 표시부(8)에 과전류상태 메세지를 출력하는 동시에 전류제어명령을 PWM제어부(9)로 출력하여 펄스폭을 변화시켜 전류를제어하고(S60~S80), 상기 하한전류 감지센서(5A)로부터 감지신호가 입력된 경우에는 표시부(8)에 최소전류상태 메세지를 출력하고 사용자로부터의 제어에 의하여 출력전류를 상승시킨다(S90~S100).Next, the microcomputer 6 checks whether a detection signal is input from the lower limit current sensor 5A and the upper limit current sensor 5B in the normal mode (S50), and detects the upper limit current sensor 5B. When a signal is input, an overcurrent status message is output to the display unit 8, and a current control command is output to the PWM control unit 9 to change the pulse width to control the current (S60 to S80), and the lower limit current detection sensor ( When the detection signal is input from 5A), the minimum current status message is output to the display unit 8, and the output current is increased by the control from the user (S90 to S100).

상기한 바와 같이, 마이컴(6)의 제어에 의하여 과전류가 발생할 확률이 높은 전기분해 초기시에는 전기분해장치용 SMPS를 버스트모드로 동작시켜 과전류가 흐르는 것을 방지하고, 그 외에는 입력된 AC전압을 DC전압으로 변환하여 출력하는 정상모드로 동작시킴으로써 전기분해의 효율을 높일 수 있으며, 사용자에게 과전류상태 및 최소전류상태를 알려 이에 대한 적절한 처리를 수행하게 함으로써 최적의 전기분해 조건을 유지할 수 있다.As described above, at the initial stage of the electrolysis in which overcurrent is likely to occur due to the control of the microcomputer 6, the SMPS for the electrolysis device is operated in burst mode to prevent the overcurrent from flowing. Otherwise, the input AC voltage is applied to DC. By operating in the normal mode of converting and outputting voltage, the efficiency of electrolysis can be improved, and the optimum electrolysis condition can be maintained by informing the user of an overcurrent state and a minimum current state and performing appropriate processing thereon.
