摘　　要：高压变频器功率范围大、工况复杂、类型多、批量小，因此在设计与使用过程中与低压变频器相比存在一些差异。本文主要探讨关于目前应用最多的单元串联型交直交变频器原理和电路拓扑结构、电路相关部件的选型与计算。介绍了检测与保护电路、驱动电路及用DSP为核心实现不对称规则采用法的SPWM波形软件设计等问题。High voltage inverter power range, the complex working conditions, process and low voltage converter compared with the existence of some differences. application of most of the unit series type into rectangular converter principle and components selection and calculation. Introduces the detection and protection circuit, realize asymmetric rules using method SPWM waveform software design problem. types, small batch, so in design and use This paper mainly discusses on the present circuit topology structure, circuit related driving circuit and using DSP as the core t realize asymmetric rules using method SPWM waveform software design problem.
