DSP-based high-power driving power supply

Abstract

The invention discloses a DSP-based high-power driving power supply, and aims to solve the problems of relatively high ripple wave and switching loss, instable working state, and unfixed output parameters in the prior art. The DSP-based high-power driving power supply comprises an external transceiving unit, an EMI unit, a rectifying and filtering unit, a power factor correction unit, a main control unit and a DC-DC converter unit; the external transceiving unit comprises an infrared transceiving circuit and a WiFi transceiving circuit connected in parallel; the EMI unit comprises a fuse F1 and an EMI main circuit; the power factor correction unit comprises a power factor correction main circuit and a power factor correction control circuit; and the main control unit comprises a main control chip and a peripheral circuit connected with the main control chip. The DSP-based high-power driving power supply is low in cost, simple in apparatus, and plays an important role in improving the performance of the high-power driving power supply.

Description

technical field [0001] The invention relates to a high-power driving power supply, which belongs to the field of driving power supply, in particular to a DSP-based high-power driving power supply. Background technique [0002] With the rapid development of power electronics technology, switching power supply technology has developed rapidly due to its advantages of high efficiency, high reliability and small size, and is widely used in high-tech fields such as aerospace and medical treatment. The traditional high-power driving power supply is mainly an analog power supply. This kind of power supply has some disadvantages in terms of communication capability, stability and configuration, and its working status is unstable. However, the current high-power drive power supply on the market is mainly controlled by digital chips to generate PWM waves, and the control loop mainly relies on single-loop control. When the load power is too large, the working state is unstable and the ...

Problems solved by technology

The traditional high-power drive power supply is mainly an analog power supply. This kind of power supply has some disadvantages in terms of communication capability, stability and configuration, and its working status is unstable.

However, the current high-power drive power supply on the market is mainly controlled by digital chips to generate PWM waves. The control loop mainly relies on single-loop control. When the load power is too large, the working state is unstable and the drive power supply is damaged, which cannot meet the requirements. market demand
