直流斩波变换领城中的半桥和全桥逆变电路和调节原理是DC/AC变换中最为广泛的基础电路和调节原理,交流斩波变换领域中也有与它们相对应的龚氏半桥和全桥变换电路和调节原理,龚氏半桥双向调是原理是1个交流斩波调压电路的输出交流电压与倒相自耦变压器绕组中间抽头上的交流电压进行比较,实现交流电压正反双向调节电压的调节原理。龚氏全桥双向调节原理是2个交流斩波调压电路的输出交流电压进行比较,实现正反双向调节输出电压的原理。它们是从众多交流斩波双向调压电路发明中提炼出来的新原理,是交流电压实现双向调节电压的基础,它们包含有多种AC/AC斩波变换双向调节的新电路,在交流斩波双向调压中可节省4~12个倒相双向电子开关,使双向调压电路简化成本降低。

The half-bridge and full-bridge inversion circuit and regulation principles applied to DC chopping con-version field are the most comprehensive basic circuits and regulation principles that can be applied to DC/AC conver-sion. Similarly, the corresponding Gong5s half-bridge and full-bridge conversion circuits and regulation principles also exist in the AC chopping conversion field. In the principle of Gong’s half-bridge bidirectional regulation, the AC output voltage of an AC chopping voltage-regulation circuit is compared with the AC voltage across the center tap of a phase- inversion autotransformer ’ s winding to realize a forward-reverse bidirectional regulation of the AC voltage. In the princi-ple of Gong’s full-bridge bidirectional regulation, the two AC output voltages from two AC chopping voltage-regulation circuits are compared to realize a forward-reverse bidirectional regulation of the output voltage. These new principles are extracted from numerous AC chopping bidirectional voltage-regulation circuits, which are foundations for realizing a bidirectional voltage-regulation and contain various new bidirectional regulation circuits of AC/AC chopping conversion. Therefore, 4- 12 bidirectional phase-inversion electronic switches can be saved in the AC chopping bidirectional voltage - regulation, which simplifies the bidirectional voltage-regulation circuits and reduces their cost.
