【摘要】 提出了一种采用新颖的Z源逆变方式应用于万能式断路器的测试电压源。利用Z源独特拓扑将直流电压源和逆变器主电路相耦合,结合相应的控制方法可以使逆变输出正弦交流电压高于直流侧的母线电压,扩大了输出电压的调节范围,同时又能实现调频、调幅、调相等控制功能。更多还原

【Abstract】 A novel kind of test voltage source which adopted Z source inversion mode in air circuit breaker was put forward.Coupling DC voltage source with the inverter’s main circuit by using Z sources’unique topology,combined with the corresponding control method to make the output sinusoidal AC voltage higher than the inverter’s DC side of the bus voltage,the test source expanded its output voltage range while achieving adjustable frequency,amplitude,phase and other control functions.更多还原
