Description

열전소자를 이용한 전압 공급 시스템{SYSTEM FOR SUPPLYING VOLTAGE BY USING THERMOELEMENT}Voltage supply system using thermoelectric elements {SYSTEM FOR SUPPLYING VOLTAGE BY USING THERMOELEMENT}

본 발명은 소손된 열전소자 셀 채널을 검출하고, 해당 불량 열전소자 셀 채널의 교체없이 전압을 승압하여 정상적으로 출력 전압을 생산하도록 할 수 있는, 열전소자를 이용한 전압 공급 시스템에 관한 것이다.The present invention relates to a voltage supply system using a thermoelectric element that can detect a burned-out thermoelectric element cell channel and boost the voltage to normally produce an output voltage without replacing the defective thermoelectric element cell channel.

통상, 제벡 효과(Seebeck effect)는 열전모듈의 열전소자의 양단에 온도차가 발생하면 열기전력이 발생하는 현상으로, 열전모듈의 가열부는 복사열, 대류열 등에 의해 가열되고, 냉각부는 냉각수, 공기 등에 의해 냉각될 수 있다.Typically, the Seebeck effect is a phenomenon in which thermoelectric power is generated when a temperature difference occurs between both ends of the thermoelectric elements of a thermoelectric module. The heating part of the thermoelectric module is heated by radiant heat, convection heat, etc., and the cooling part is heated by coolant, air, etc. It can be cooled.

한편, 종래기술에 의한 열전소자를 이용한 전압 공급 시스템은, 도 1에 예시된 바와 같이, 직렬 연결된 열전소자 셀 채널(11)로 이루어진 열전소자부(10)로부터 생산된 전력을 블로킹 회로(20)와 MPPT(Maximum Power Point Tracking)(30)을 통해 배터리(40)에 저장하고, 전력변환기(50)로 공급하도록 한다.On the other hand, the voltage supply system using a thermoelectric element according to the prior art, as illustrated in FIG. 1, uses a blocking circuit 20 for power produced from the thermoelectric element unit 10 consisting of thermoelectric element cell channels 11 connected in series. and MPPT (Maximum Power Point Tracking) 30 to store it in the battery 40 and supply it to the power converter 50.

It is impossible, and even if the defective thermoelectric element cell channel 11 is detected by an external terminal, the worker cannot access the defective thermoelectric element cell channel 11 due to safety issues due to the high temperature, and the thermoelectric element unit 10 All must be removed, which reduces economic efficiency in operating power generation facilities.

이에, 해당 불량 열전소자 셀 채널의 교체없이 전압을 승압하여 정상적으로 출력 전압을 생산하도록 할 수 있는 기술이 요구된다.Accordingly, there is a need for a technology that can properly produce output voltage by boosting the voltage without replacing the defective thermoelectric element cell channel.

이하, 도면을 참조하여, 전술한 구성의 열전소자를 이용한 전압 공급 시스템을 구체적으로 상술하면 다음과 같다.Hereinafter, with reference to the drawings, the voltage supply system using the thermoelectric element of the above-described configuration will be described in detail as follows.

우선, 열전소자부(110)는, 도 2 및 도 3을 참고하면, 다수의 열전소자 셀 채널(111)이 직렬 연결된 2개 이상의 열전소자그룹(112)이 병렬 연결되어, 태양광, 소각장의 폐열, 화학 플랜트의 폐열, 제철소의 폐열 등의 산업체에서 발생하는 폐열을 열원으로 하여, 온도차에 의해 전기에너지를 생성하여 전력을 생산하도록 한다.First, referring to FIGS. 2 and 3, the thermoelectric element unit 110 consists of two or more thermoelectric element groups 112 in which a plurality of thermoelectric element cell channels 111 are connected in series, and is connected in parallel to provide solar power and an incinerator. Waste heat generated from industries, such as waste heat, waste heat from chemical plants, and waste heat from steel mills, is used as a heat source to generate electrical energy through temperature differences to produce electricity.

다음, 전압센서(120)는, 도 4 및 도 5를 참고하면, 각 열전소자 셀 채널(111)별로 병렬 연결되어 해당 열전소자 셀 채널(111)의 불량여부를 측정하는데, 예컨대, 직렬 연결된 다수의 저항(121)을 포함하여 저항(121)에 의한 전압값에 따라 해당 열전소자 셀 채널(111)의 소손 또는 노화에 따른 전압강하를 식별하도록 할 수 있다.Next, referring to FIGS. 4 and 5, the voltage sensor 120 is connected in parallel for each thermoelectric element cell channel 111 to measure whether the thermoelectric element cell channel 111 is defective. For example, a plurality of voltage sensors 120 connected in series are connected in parallel. It is possible to identify the voltage drop due to burnout or aging of the thermoelectric element cell channel 111 according to the voltage value of the resistor 121, including the resistor 121.

한편, 도 4 및 도 5에 예시된 바와 같이, FET 온오프 회로(162)별로 결선되어, 열전소자 셀 채널(111)별 출력전압을 모니터링하고, FET 온오프 회로(162)를 특정 전압 이하로 제어하는 절연 DC/DC 컨버터(122)와 절연 포토 커플러(123)를 더 포함하여서, 절연 DC/DC 컨버터(122)와 절연 포토 커플러(123)를 통해, 수십 개 이상으로 직렬 연결되어 그룹핑된 열전소자그룹(112)의 수백 V 이상의 전압으로부터 보호하기 위해 내압 설계되도록 하며, 열전소자 셀 채널(111)별로 단위 출력전압, 예컨대 5V 단위로 모니터링하고 제어하도록 할 수 있다.Meanwhile, as illustrated in FIGS. 4 and 5, each FET on-off circuit 162 is wired to monitor the output voltage for each thermoelectric cell channel 111, and the FET on-off circuit 162 is controlled below a specific voltage.

도 4에 예시된 바와 같이, 능동 승압부(140)는, 열전소자부(110)로부터 입력되는 강하 전압을 승압하여 보상하는 저항회로(141)와, 저항회로(141)에 의한 승압을 제어하는 PWM(pulse width modulation) IC(142)로 이루어져서, PWM IC(142)는, 열전소자그룹(112)의 정상적인 전력 생산에 해당하는 특정 전압에 미치지 못하는 불량 열전소자 셀 채널(111)에 의한 전압 강하만큼, 저항회로(141)에 의한 출력 전압을 제어하여서, 최대 입력 전압의 2배까지 부스팅하여 전압을 승압하도록 할 수 있다.As illustrated in FIG. 4, the active boosting unit 140 includes a resistor circuit 141 that boosts and compensates for the voltage drop input from the thermoelectric element unit 110, and a resistor circuit 141 that controls the boosting by the resistor circuit 141. It consists of a pulse width modulation (PWM) IC 142, which reduces the voltage drop caused by the defective thermoelectric element cell channel 111 that does not reach a specific voltage corresponding to normal power production of the thermoelectric element group 112. By controlling the output voltage by the resistance circuit 141, the voltage can be boosted by boosting up to twice the maximum input voltage.

다음, 전력변환기(150)는 능동 승압부(140)에 의해 승압된 전력의 전류, 전압 또는 주파수를 변환하여 전력을 변환하도록 한다.Next, the power converter 150 converts the current, voltage, or frequency of the power boosted by the active booster 140 to convert power.

다음, 스위치부(160)는, 도 3 및 도 4를 참고하면, 열전소자 셀 채널(111)별로 병렬 연결되어 상호 직렬 연결되고, 전압센서(120)에 의한 불량 측정시에, 해당 불량 열전소자 셀 채널(111)을 바이패스하여 전력 저장부(130)에 결선되도록 한다.Next, referring to FIGS. 3 and 4, the switch unit 160 is connected in parallel for each thermoelectric element cell channel 111 and connected in series to each other, and when a defect is measured by the voltage sensor 120, the defective thermoelectric element The cell channel 111 is bypassed and connected to the power storage unit 130.

구체적으로, 스위치부(160)는, 열전소자 셀 채널(111)별로 병렬 연결된 FET 스위치(161)와, 전압센서(120)에 의한 측정값에 따라 FET 스위치(161)를 스위칭하는 FET 온오프 회로(162)로 구성되어, FET 스위치(161)의 온시에, 불량 열전소자 셀 채널(111)을 전기적으로 단락시키도록 하여서, 불량 열전소자 셀 채널(111)에 의해 전압 강하된 열전소자그룹(112)의 출력 전압이 능동 승압부(140)에 의해 승압되도록 하여, 해당 불량 열전소자 셀 채널(111)의 교체없이도 특정 전압을 생산하도록 할 수 있다.Specifically, the switch unit 160 includes a FET switch 161 connected in parallel for each thermoelectric cell channel 111, and a FET on-off circuit that switches the FET switch 161 according to the measured value by the voltage sensor 120. It is composed of (162), and when the FET switch 161 is turned on, the defective thermoelectric element cell channel 111 is electrically short-circuited, so that the thermoelectric element group 112 whose voltage is lowered by the defective thermoelectric element cell channel 111 ) can be boosted by the active booster 140 to produce a specific voltage without replacing the defective thermoelectric element cell channel 111.

예컨대, 도 3의 (b)에서와 같이, 2ch에 해당하는 열전소자 셀 채널(111)이 소손되면, FET 온오프 회로(162)가 FET 스위치(161)를 온시켜 단락시키도록 하여(0V) 열전소자그룹(112)에 의해 생산된 전력이 출력되도록 하고(15V), 능동 승압부(140)에 의해 불량 열전소자 셀 채널(111)에 의한 전압 강하를 보상하도록 하여서, 전력을 정상적으로 생산하도록 할 수 있다.For example, as shown in (b) of FIG. 3, when the thermoelectric element cell channel 111 corresponding to 2ch is burned out, the FET on-off circuit 162 turns on the FET switch 161 to short-circuit it (0V). The power produced by the thermoelectric element group 112 is output (15V), and the voltage drop caused by the defective thermoelectric element cell channel 111 is compensated by the active booster 140 to produce power normally. You can.

또한, FET 온오프 회로(162)는 포토커플러를 통해 FET 스위치(161)를 아날로그 제어하도록 할 수 있다.Additionally, the FET on-off circuit 162 can provide analog control to the FET switch 161 through a photocoupler.

따라서, 전술한 바와 같은 열전소자를 이용한 전압 공급 시스템의 구성에 의해서, 소손된 열전소자 셀 채널을 검출하고, 해당 불량 열전소자 셀 채널의 교체없이 전압을 승압하여 정상적으로 출력 전압을 생산하도록 할 수 있다.Therefore, by configuring the voltage supply system using the thermoelectric element as described above, it is possible to detect a burnt-out thermoelectric element cell channel and boost the voltage without replacing the defective thermoelectric element cell channel to normally produce an output voltage. .
