The improved rectifier circuit is characterized in that the alternating current input is connected with a generator, the generator is connected with an energy release control portion, and the energy release control portion is connected with the current output; the energy release control portion comprises a three-phase diode rectifier bridge, a low pass filter and a direct current step-down chopper, the direct current step-down chopper is further connected with a pulse width modulation output controller, the pulse width modulation output controller is connected with a triangular wave direct current comparison controller, the triangular wave direct current comparison controller is further connected with rotating speed signals and output voltage feedback signals, and the generator is further connected with a control system. The improved rectifier circuit has the advantages of being simple and convenient to operate, smooth and stable in whole operation, safe, reliable, and low in manufacture cost.

Description

technical field [0001] The invention relates to the field of rectifiers, in particular to an improved rectifier circuit. Background technique [0002] A rectifier is a rectifying device, simply put, a device that converts alternating current into direct current. It has two main functions: first, it converts alternating current into direct current, and supplies the load or inverter after filtering; second, it provides charging voltage for the battery. Therefore, it also acts as a charger at the same time, which can be used for power supply and detection of radio signals, etc., and can also be made of vacuum tubes, ignition tubes, solid-state silicon semiconductor diodes, mercury arcs, etc. The rectifier circuit is an important part of the rectifier device, and the quality of the rectifier circuit directly affects the result of the rectifier. The rectifier circuit in the prior art is complex in operation, difficult in operation, high in risk, unstable in overall operation, a...
