Due to the power electronic technology is the electronic technology and control technology is introduced into the traditional electric power technology, using power semiconductor switching devices of all kinds of electricity power conversion circuit implementation and control, and transform, constitute a complete discipline.So their learning methods and electronic technology and control technology has many similarities, so if you wa
