项目摘要

Various methods have been proposed on circuit technique for suppression of input current harmonics to electronic equipment using switching device. The purposes of this study are as follows, (1) To develop new electronic ballast that can satisfies IEC standard class C for the lighting equipment, and (2) To examine the feasibility of applying developed inverter circuit to general power supply circuit.In the first planning year, the electronic ballast that can satisfy IEC standard by adding charge-pump function to the push-pull inverter circuit has been developed. Charge-pump function is operated using the high frequency voltage that arises at the constant-current inductor in the push-pull circuit. When high frequency voltage is applied in the middle point of two small capacitors that are placed parallel with the input power, two capacitors repeat charge and discharge. As result, the current can flow into the circuit even when the input voltage is low.In the second planning year, the other new electronic ballasts have been developed that can also satisfy IEC standard. A step-down converter and a buck-boost converter for electronic ballast have been developed by improvement of neutral-point-type boost-converter that was proposed by authors. In addition, by analyses of circuit operations of push-pull inverter having charge-pump function, the feasibility of applying this circuit to general power supply circuit was examined. The power supply circuit for several lamps was made, and the experiment is being carried out at present.

为了利用开关器件抑制电子设备的输入电流谐波，在电路技术方面提出了各种方法。本研究的目的是：(1)为照明设备开发符合IEC标准C类的新型电子镇流器；(2)考察所开发的逆变电路应用于通用电源电路的可行性。在第一个规划年，通过在推挽逆变电路中加入电荷泵功能，开发出符合IEC标准的电子镇流器。电荷泵功能是利用推挽电路中恒流电感上产生的高频电压来运行的。当在与输入功率平行的两个小电容器的中点施加高频电压时，两个电容器重复充电和放电。因此，即使在输入电压较低的情况下，电流也可以流入电路。在第二个规划年，其他新的电子镇流器已经开发出来，也可以满足IEC标准。通过对作者提出的中点型升压转换器的改进，研制了一种用于电子镇流器的降压和降压升压转换器。此外，通过对具有电荷泵功能的推挽式逆变器电路运行的分析，验证了该电路应用于一般电源电路的可行性。制作了几种灯具的电源电路，目前正在进行实验。
