Problems solved by technology

[0003] At present, the analog control technology of switching power supply is very mature, and the market share of analog control chips is also very high, but analog control chips generally only correspond to one control mode, and the redesign of the main circuit often requires the redesign of the control circuit, increasing Reduced the complexity and workload of power supply design
[0004] At the same time, during the debugging process of switching power supply, it is necessary to constantly modify parameters such as PWM cycle, dead zone, and PID. Analog control can only realize the modification of parameters by modifying the corresponding hardware such as capacitors and resistors. It is inconvenient and reduces the debugging efficiency. On the one hand, it also reduces the control of product quality. Moreover, the current power switch debugging device is bulky and inconvenient to carry.

Abstract

The invention relates to a digital power control method, device and system. The method comprises the following steps of acquiring an initial voltage and a control mode of a to-be-debugged power; debugging the initial voltage according to the control mode and a pre-stored PID control algorithm, so as to obtain a PWM signal corresponding to the control mode; and controlling at least one of voltage, current, temperature and failure information in the debugging process of the initial voltage, and sending the at least one information to a terminal to display. Through adoption of the digital power control method, device and system, the debugging efficiency is improved, the design workload and design complexity of a control circuit of a switch power are lowered, the power can be debugged in a long distance, and the power can be debugged more portably and efficiently.

Description

technical field [0001] The present invention relates to the field of power supply control, in particular to a digital power supply control method, device and system. Background technique [0002] With the development of power supply technology, the radar power supply has changed from a very bulky linear power supply to a switching power supply commonly used today. [0003] At present, the analog control technology of switching power supply is very mature, and the market share of analog control chips is also very high, but analog control chips generally only correspond to one control mode, and the redesign of the main circuit often requires the redesign of the control circuit, increasing The complexity and workload of power supply design are reduced. [0004] At the same time, during the debugging process of switching power supply, it is necessary to constantly modify parameters such as PWM cycle, dead zone, and PID. Analog control can only realize the modification of parame...
