Analysis on the Commutation Process of the Single-phase Rectifier Circuit and its Application

With the maturity and popularization of the technology of power electronic transformation, the power drag, rectifier circuit is used in great quantities in the application fields such as power system, which is including diode uncontrolled rectifier circuit, voltage type PWM rectifier circuit. To stabilize the DC voltage loop, the high-power power electronic converter requires the use of high capacity values of the electrolytic capacitor. Therefore in the rectifier circuit electric surge current limiting measures must be taken, otherwise it will cause the movement, the air switch fuse burn out, the problem such as line loss is too large, also due to the presence of stray inductance level inverter circuit over-voltage breakdown after making. This paper will focus on the single-phase rectifier circuit fazed rectifier circuit and inverter structure, properties, and other elements and single phase rectifier circuit selection factors in the process of application.
