A new concept of litz copper foils is proposed to reduce AC winding losses of high frequency power transformer in high current low voltage switch-mode power supply. 提出一种应用于低压大电流高频开关电源功率变压器的新型双绞并联铜箔线圈。
A design for resonant inductor used litz wire with optimum winding loss was improved, and 4% efficiency was increased by comparison to the initial design with a series resonant inverter at 1 kVA. 改进、设计了一种高频串联谐振型逆变器的谐振电感器,在1kVA容量时,使逆变器整机效率提高了4%。
