| Abstract: | Aiming at the demerits of lowering voltage by using transformer on AC side in three phase voltage source PWM rectifier,a new method of DC link in rectifier with bidirectional voltage converter substituting transformer in AC side is presented, topology and operating principle of converting circuit and system circuit are introduced.The circuit is fit for the PWM rectifying and inverting situation at which the power should flow in two direction.The simulation and experimental results prove that the method is simple and feasible. |
