Abstract
본 발명은 용량성 부하를 가지는 전류형 인버터의 사이리스터 인버터부에 사용하는 기동회로에 관한 것으로서, 특히 오존 발생기용 전원장치에 적용되는 전류형 인버터에서 발생되는 스위치 교번실패를 방지할 수 있도록 한 인버터부 기동장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a starter circuit for use in a thyristor inverter section of a current inverter having a capacitive load, and in particular, an inverter section capable of preventing a switch alternation failure generated in a current inverter applied to a power supply device for an ozone generator. It relates to a starting device.
종래에 오존 발생장치는 용량성 부하에 대응하기 위하여 전류형 인버터를 이용하는 전원장치를 사용하는데, 이 전류형 인버터의 기동회로에서는, 초기 상태에 부하의 전압 형성 및, 그 형성된 전압이 스위치 교번에 필요 충분한 역전압인지를 감지하는데 어려움이 있고, 이로 인하여 부하 단락이 발생하여 시스템 다운이나 손상 등의 영향을 미치는 문제점이 있다.Conventionally, the ozone generator uses a power supply device using a current inverter to cope with a capacitive load. In the starting circuit of the current inverter, the voltage of the load is formed in the initial state and the voltage formed is required for the switch switching. There is a difficulty in detecting whether there is sufficient reverse voltage, which causes a short circuit to cause a system down or damage.
본 발명은 상기한 종래의 문제점을 해결하기 위하여, 마이크로 프로세서에 의한 충전 예측시간을 예측하여 충전 요구 시간에 해당되는 신호를 인버터 스위칭 명령으로 제공함으로써 기동시 스위치 교번에 필요한 충분한 역전압이 형성되도록 인버터부 스위칭 시이퀀스를 제어하고, 이것에 의하여 출력 전압 감지에 의한 사이리스터 전류형 인버터의 스위치 교번 실패를 방지할 수 있도록 한 용량성 부하를 가지는 전류형 인버터의 인버터부 기동장치를 제공한다.In order to solve the above-mentioned problems, the present invention predicts the charge prediction time by the microprocessor and provides a signal corresponding to the charge request time to the inverter switching command so that a sufficient reverse voltage necessary for switch switching at startup is formed. An inverter unit starting device for a current inverter having a capacitive load which controls the secondary switching sequence and thereby prevents the switch alternation failure of the thyristor current inverter due to the output voltage sensing.
