一种基于功率器件周期性交替使用的H桥变换器温升平衡与最小化PWM方法

Aiming at the temperature rise and thermal control issues of power devices in H-bridge converters under conventional pulsewidth modulation (PWM) methods, a novel PWM method of H-bridge converter with temperature rise balancing and minimization based on periodically alternating employment of power devices is proposed. In the proposed method, two novel operation mechanisms of power devices are alter...
