【摘要】 研究中发现了电源电压频率异常现象。通过实验发现这种现象是由于高漏感变压器的存在,导致电路谐振能量过大引起的。在此研究了这种现象对开关损耗和RCD缓冲电路的影响,提出通过调整谐振参数和加大占空比来抑制这种现象的方法。更多还原

【Abstract】 During the researching process,the unusual voltage-frequency phenomenon of the power supply is discovered. The experiments confirm that this phenomenon is caused by the over-charging oscillation as a reason of the highleakage transformer.The influence of this phenomenon to the switching loss and the RCD buffer circuit is discussed. And for eliminating the influence,adjusting the parameter of oscillation and increasing the duty cycle is suggested.更多还原
