| 1. | The zero - voltage - switching ( zvs ) pwm hybrid full - bridge three - level ( h - fb tl ) converter can operate in both three - level mode and two - level mode , the output rectified voltage is close to the output voltage over the entire input voltage range , thus the output filter can be reduced significantly , leading to high power density and fast dynamic response . so the zvs pwm h - fb tl converter is very attractive for the applications such as fuel cells , photovoltaic cells , and telecom power supplies , where the voltage varies in a wide range
零电压开关复合式全桥三电平( zero - voltage - switchingpwmhybridfull - bridgethree - level , zvspwmh - fbtl )变换器可以工作在三电平模式和两电平模式,在很宽的输入电压范围内,输出整流电压都接近输出电压,从而可以减小输出滤波器,因此可以提高变换器的功率密度和改善动态性能。 |
