Method for improving voltage modulation of power supply system

Abstract

The invention discloses a method for improving voltage modulation of a power supply system, which belongs to the field of low-voltage power supply system and large dynamic load power supply, and comprises the following steps: S1, arranging a BOOST circuit in an active energy storage module; s2, detecting the current of the main circuit, and when the current at the ending moment of the large power consumption stage of the dynamic load is detected, charging an energy storage capacitor by using a digital control BOOST circuit, and controlling the charging slope by controlling the opening time of the BOOST circuit, so that the generator can respond to the power change; and when it is detected that the dynamic load is in the high power consumption stage, the discharge process of the energy storage capacitor is controlled through the BUCK circuit. Energy can be efficiently utilized, the efficiency of a power system is improved, the pressure of a heat dissipation system is reduced, and the purpose of normal power supply of a matching system is achieved.

Description

technical field [0001] The invention relates to the field of low-voltage power supply system and large dynamic load power supply, and more particularly, to a method for improving voltage modulation of a power supply system. Background technique [0002] When the number of T / R elements of the transmitter is small, the power is small. If it is much smaller than the output power of the generator, or the working repetition frequency of the transmitter and receiver is high (≥5KHz), the influence on the generator will be relatively small. Small. However, in the electronic work, the working repetition frequency of the transmitter and receiver must be ≤5KHz, and with the development requirements of the equipment, the transmission power will become larger and larger. When the large dynamic change reaches about 20% of the generator power, it will have a great impact on the generator, causing the generator to oscillate, resulting in modulation, affecting the entire power supply system...
