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.

在电路技术上已经提出了多种方法来抑制使用开关装置的电子设备的输入电流谐波。本研究的目的如下：(1) 开发能够满足照明设备 IEC C 级标准的新型电子镇流器；(2) 检验将开发的逆变器电路应用于通用电源电路的可行性。计划第一年，通过在推挽式逆变电路中添加电荷泵功能，开发出满足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器产生的高频电压来操作的。当高频电压施加在与输入电源并联放置的两个小电容器的中点时，两个电容器重复充电和放电。因此，即使输入电压较低，电流也能流入电路。在第二个规划年里，又开发了其他也能满足IEC标准的新型电子镇流器。通过对作者提出的中点型升压变换器的改进，研制出了用于电子镇流器的降压变换器和升降压变换器。另外，通过对具有电荷泵功能的推挽式逆变器的电路操作进行分析，检验了该电路应用于通用电源电路的可行性。制作了多盏灯的供电电路，目前正在进行实验。
