| 摘 要： | 提出了一种前端LCL谐振式变换器,其前级为功率因数校正（PFC）,后级为采用数字控制的逆变器。设计并制作了一台AC220V输出的1kW试验样机,对实验样机测试的结果表明,前级升压电路实现了零电压开通（ZVS）,后级电路实现了闭环控制,整个系统动态与稳态性能均较好,理论分析正确。

| Abstract: | A front-end LCL resonant converter is proposed.Its former level is a power factor correction(PFC),while the latter level is a digital control inverter.A testing prototype with AC 220 V output and 1 kW load is designed and produced.The experimental prototype test result shows that the former level booster circuit realizes zero voltage soft switching,and the latter level circuit achieves closed loop control.The dynamic and static performance of the whole system is excellent,which proves the correct of theoret... |
