  1. At last , a novel zvs isolated boost converter is presented . this converter is employed the lcd snubber circuits and coupled winding in boost inductance , the switches can realize zero voltage turn off and the surge voltage of switch is low . the principle of this converter is analyzed in detail
    最后深入研究了一种适合于低压大电流输入场合的隔离型boost变换器,分析了它的优点和缺点,在此基础上提出了一种新型隔离型zvsboost变换器,详细分析了其工作原理,给出了参数设计,仿真和样机实验结果验证了方案的正确性。
  2. " soft switching " is zero voltage switching or zero current switching , which the voltage ( or current ) of the switch varies by law of sine or quasi sine , the switch is on when its voltage reaches zero ( or switch is off when its current reaches zero ) by resonance . it makes switch loss is zero , so it can increase the operating frequency and raise power density , minimize the size of transformer and inductor
    “软开关”是指零电压开关或零电流开关,它是利用谐振原理,使开关变换器的开关管电压(或电流)按正弦(或准正弦)规律变化,当电压过零时,使器件开通(或电流自然过零时,使器件关断) ,实现开关损耗为零,从而提高开关频率,减小变压器、电感的体积。
