Abstract

The invention relates to a dual-circuit chopping-wave and voltage-regulating power electronic module. The power electronic module comprises a voltage-regulating signal interface circuit used for receiving two paths of voltage signals, a PWM control circuit used for outputting two paths of PWM control signals, a driving circuit used for outputting four paths of PWM driving signals, a dual-circuit synchronous rectifying BUCK circuit used for outputting two paths of high-frequency chopping-wave PWM voltages, and a voltage and current sampling circuit used for collecting two paths of high-frequency chopping-wave PWM output voltage signals. The power electronic module adopts two-circuit PWM independent control and two-circuit chopping-wave and voltage-regulating circuit integration; the average output voltage is controlled by adjusting duty ratio; the rotary speeds of a vehicle-mounted air conditioner evaporation fan and a condensation fan are regulated flexibly; and in addition, the power electronic module is small in size, compact in structure, efficient, convenient to install, and capable of promoting resource optimization configuration of a vehicle-mounted system.

Description

technical field [0001] The invention relates to a power electronic module for dual-circuit chopping and voltage regulation, and belongs to the technical field of vehicle-mounted DC-DC power supplies. Background technique [0002] New energy vehicles are currently entering a stage of rapid development, and the state has introduced various incentive policies to support the development of new energy vehicles. It is of great significance to energy saving, emission reduction and green environmental protection. The new energy vehicle air conditioner is an important component and a large energy consumption system. In order to improve the endurance of the new energy vehicle and save electricity, it is necessary to upgrade the vehicle air conditioner system with energy-saving technology, such as using variable frequency drive technology to drive the air conditioner compressor. Adopt DC chopper speed regulation to drive air conditioning condensing fan and evaporating fan, etc. [00...
