摘要
单相和多相桥式相控整流电路是教科书可控整流电路中的一大类性能最好的电路，也是社会上应用最多的一类电路，它在应用中给电网制造了大量感性电流和谐波电流，严重污染电网，影响电网供电质量。如何减少感性电流和谐波电流，成为电力电子基础电路和电源研究的重点。笔者在中国电源学会第20届学术年会上宣读的“导通角控制与熄灭角控制的复式可控整流电路研究”一文中对单相全波与桥式相结合的“龚氏桥全电路”已做了论述，笔者还将在上述研究的基础上对“龚氏桥式电路”和“龚氏半波电路”进行阐述，这样就构成一个完整的绿色相控电路体系，为“传统相控电源”向“绿色相控电源”转变提供理论和技术支持。
Single-phase and multi-phase controlled rectifier circuits are the one category that has the best performance among the controlled rectifier circuits in the textbook, and that is also the most widely used. But they create a lot of inductive and harmonic currents to the grid, which seriously pollutes the grid and affects its power supply quality. So how to reduce inductive and harmonic currents has become the research focus of power electronic circuits and power sources. The ＂Gong＇s full-bridge circuit＂ combining the single-phase full-wave with the bridge types has been expounded in the paper ＂Research of Extinction-Angle-and- Conduction-Angle-controlled Rectifier Circuits＂, which was read out in the 20th annual academic meeting of China Power Supply Society. Based on the above research, the author further describes the ＂Gong＇s bridge circuit＂ and the ＂Gong＇s half-wave circuit＂, so that a complete green phase-controlled circuit system is built up, to provide theoretical and technical supports for the change from ＂traditional phase-controlled power sources＂ to ＂green phase-controlled power sources＂.
