The invention relates to a multi-pulse wave rectifier using active power factor correction technology and a design method thereof, and belongs to the field of electric and electronic technology. Problems of complex control strategies of a harmonic compensation circuit and system and unadjustable output voltage during harmonic compensation on an alternating-current side of the current multi-pulse wave rectification system are solved. According to the invention, angle/star-connection transformers are used as phase-shifting transformer, and a voltage increasing chopper circuit is used on the output side of a rectification ridge to control the output current of the rectification bridge, thereby achieving the objective to inhibit current harmonic waves on the alternating-current side, and allowing the output voltage of the rectifier to be adjustable. The multi-pulse wave rectifier is simple in structure and easy to realize; harmonic content of the original multi-pulse wave rectifying system is effectively reduced; the multi-pulse wave rectifier is characterized by adjustable output voltage and can be used in a large-power occasion highly demanding electric energy quality.
