| 摘 要： | H桥级联型多电平逆变器由于具有良好的输出波形得到广泛运用,对直流电压相等的H桥级联型逆变器,当H桥直流电压由于功率元器件差异或运行过程中负载瞬时突变等出现不等或波动时可能引起输出电压、电流波形变化,各H桥输出功率不等,严重时甚至损坏变频器.对于H桥级联型多电平逆变器传统的控制方式都是建立在H桥直流电压相等的前提下,研究了H桥直流电压不等的情况,提出了适合直流电压不等的一维矢量调制技术和直流电压不等时实现H桥等功率输出的一维矢量调制.提出的方法在两单元级联型变频实验装置上进行了验证.

| Abstract: | H-bridge cascaded multilevel inverters has been widely used for good output waveform.For the H-bridge cascaded inverter with equal DC voltage,power components difference or the load transient mutation during operation may cause the distortion of output voltage and current,the output power ranging of H-bridge or even serious damage to inverter.For the H-bridge cascade multilevel inverter traditional control methods are built on the H-bridge DC voltage equal to the premise.One-dimensional vector modulation te... |
