| Abstract: | The digital control technique of single chip microcomputer is organically merged into the design of DC voltage-stabilized power supply. A multifunctional, digitalized, commonly used DC voltage-stabilized power supply with higher performance/cost ratio is successfully designed . The test shows a voltage regulation ratio of 0.015%; a load regulation ratio of 0.05%; a ripple rejection factor of 80 dB; and a maximum error between display voltage and output vollage less than 0.05 V within normal range of service. The system has such advantges as low in output resistance, low in power consumption, good in versatility, high in reliability, simple in circuit, low in cost, and directly perceived and convenient in operation. |
