Abstract:

提出一种采用3个开关管的推挽式(three-transistorsPush-Pull,TTPP)变换器,仅需要在传统推挽变换器的输入电源和变压器两个原边绕组中点间插入一个辅助开关管Q3。两个主管驱动信号ugs1和ugs2与传统推挽变换器中开关管的驱动信号相反;除去死区时间,辅管驱动信号ugs3是两个主管驱动信号ugs1和ugs2的与非关系。用等效电路的方法结合解析方程,分析电路各个工作模态的工作原理和主要开关波形。指出主管可在宽负载范围下实现零电压开通(zerovoltageswitching,ZVS),且主管关断电流是传统推挽电路中的一半值。辅管在大负载或加大漏感情况下可以实现ZVS开通,辅管的额定电压是主管的一半,等于输入电压。讨论软开关的实现问题。提出控制芯片及其驱动电路的设计方法,完成一台800?W、开关频率为83.3?kHz的原理样机,实验结果验证了该变换器工作原理的有效性。
