逆变电源开关损耗的分析与对策

在大功率高频道变电源电路中．开关管的开关损耗成为限制整机效率、功率和功率密度的重要因素，并直接影响整机的安全运行．在分析桥式逆变电路开关管工作过程和开关损耗的基础上，提出了一种新的开关工作模式和吸收网络设计，使电路工作在近似零压开关的状态，有效地减小了开关损耗．

Discussion and Solution: Switching Consumption of Inverter Power Supply

Switching consumption becomes important to the power density and power efficiency of high frequency inverter power supply. It also affects the safety of inverter. The switching consumption of H-type inverter is discussed. As a solution, a new pattern of switching sequence and a new design of absorb circuit are raised. These methods enable the circuit to switch on or off under zero voltage and thus the switching consumption deduced.
