一种单相软开关逆变器的自适应开关频率与导通损耗优化调制策略

Single-phase full-bridge inverter operating in triangular current mode (TCM) can realize zero-voltage switching to achieve high efficiency. However, the TCM full-bridge inverter features a wide range of switching frequency variation, especially near the ac current zero-crossing point (ZCP), which increases the switching loss and control difficulty. In this article, an adaptive optimal quasi-trapez...
