【摘要】 首先分析Flyback变换器中漏感对主开关端电压和效率的影响,比较几种漏感能量吸收电路的优缺点,在此基础上提出并分析一种新型漏感能量吸收电路。在吸收漏感能量、消除主开关电压尖峰的同时,将吸收的能量提供给控制电路,提高了效率。并通过试验验证了这一电路的效果。更多还原

【Abstract】 A novel leakage inductance absorbing circuit was proposed and analyzed. Compare d with other type absorb circuits,some features can be achieved in flyback conver ters using this circuit such as system efficiency can be higher,the voltage spik e across the main switch can be eliminated and a stable power supply for control circuit can be achieved. These merits were verified through the experiment res ult.更多还原
