Abstract

This application provides a transient voltage improvement circuit and power supply system, relating to the field of power supply technology. The transient voltage improvement circuit includes a power supply module, a first comparison module, a second comparison module, a charging module, and a discharging module. The power supply module supplies power to the load through a main power supply circuit. The first and second comparison modules are both connected to the main power supply circuit, as are the charging and discharging modules. The first comparison module is connected to the charging module, and the second comparison module is connected to the discharging module. The first comparison module controls the charging module to operate when the voltage of the main power supply circuit is lower than a first threshold voltage, charging the main power supply circuit at a fixed current. The second comparison module controls the discharging module to operate when the voltage of the main power supply circuit is higher than a second threshold voltage, discharging the main power supply circuit at a fixed current. The solution provided in this application has the advantages of low implementation difficulty, lower circuit cost, smaller area, and lower power consumption.
