摘要
根据负载功率调节的要求,提出了频率跟踪型移相PWM控制策略,并分析了基于该控制下单相全桥逆变器主电路的工作状况,对提出的实现软开关的电路进行了参数计算、仿真和实验。该电路具有性能优越,实现简单可靠等优点。
According to the demand of power adjustment, the frequency tracing phase-shifted PWM control strategy is proposed, the working status of the main circuit in the single-phased full-bridge inverter based on the control is analyzed, and the parameter calculation, simulation and experiment of the circuit which implemented soft switching have done. The superiority performance and it is much easy and reliable to implement are verified by experimental result
