| Abstract: | In order to reduce the output voltage ripple and improve the efficiency of the whole system, Digital power supply is designed by using DC-DC converter circuit series LDO circuit, which combine switching power supply and linear power supply, taking into account the advantages of both. Adopting fuzzy adaptive control algorithm to control DC-DC converter circuit and linear regulator circuit realize the intelligent power supply. The test results show that the system has advantages of good output stability, high control accuracy, high efficiency and good application value. |
