控制电路的设计质量对变频器的性能至关重要。应该作为设计工作的重点同时控制电路功能众多,相对复杂,设计的内容比较复杂,周期较长,甚至可能出现反复,有时一些参数的确定还需要通过实验来得到考虑到变频器的通用功能设计已经是非常成熟的东西,所以,主要描述了和软开关技术相关的控制电路设计 The quality of the control circuit design is crucial to the performance of the drive. Should be the focus of the design work at the same time control the circuit function is numerous, relatively complex, the design of the content is more complex, longer cycle, and may even be repeated, and sometimes some parameters need to be determined through experiments to take into account the general function of the inverter has been designed Is a very mature thing, so, mainly describes the control circuit design and soft switching technology
