| 摘 要： | 针对传统的三相AC/AC变频电路特点,提出了一种新的电路拓扑,仅用6个功率器件即可实现三相AC/AC变频功能.提出基于脉冲阻塞原理的等脉宽斩波控制策略,取代传统的移相控制策略施加于该电路拓扑,实现了三相输出电压幅值、频率分别可调或同时可调.对等脉宽斩波控制策略进行了详细的理论分析.根据期望输出电压的不同频率和幅值.利用...

| Abstract: | A circuit topology of three-phase AC / AC system is presented,which needs only six power devices to realize the three-phase AC / AC frequency conversion.The traditional phase-shifted control strategy is replaced by the equal pulse width chopping control strategy based on plugged pulse principle to regulate the amplitude and frequency of output voltage separately or simultaneously.The equal pulse width chopping control strategy is analyzed in detail and the mathematic expression of duty cycle is deduced base... |
