一种用于异步并联半桥电路的无缝热平衡控制策略

The asynchronous parallel half-bridge circuit has the characteristics of reliable capacity expansion and easy realization of zero-voltage switching, which can be a promising candidate for large capacity converters using wide bandgap devices. However, it has the issue of heat concentration, which leads to severe thermal imbalance and high thermal stress, posing a challenge to thermal design. In thi...
