摘　　要：阐述了正交型变压器自激励振方式电流谐振型软开关变换电源技术.重点解析了CRC的电感控制、开关变换频率控制、电流串联谐振频率控制这3种典型控制方式和新型复谐振型软开关变换电源.说明了新型自激励振方式软开关变换电源所采用的3种新技术,即超小型PRT和小型PIT、开关变换驱动电路、双BJT和控制模块.The paper describes the power technique of PRT self-inspirit oscillation way CRC soft switching converter. The article mainly illustrates three typical kinds of control ways and a new style of complex resonant soft switching converter power supply. The three control ways are the control of CRC, the frequency control of converter switchgear, the frequency control of current series connection resonance. It also specially describes three types of new techniques about the power of PRT self-inspirit oscillation way CRC soft switching converter, for instance, microminiature PRT and mininature PIT, switching converter driving circuit, double BJT and control mode.
