摘要:
将单片机数字控制技术,有机地融入直流稳压电源的设计中,设计出一款高性价比的多功能数字化通用直流稳压电源 .经测试表明,其电压调整率为 0 .0 15 %,负载调整率 0 .0 5 %,纹波抑制比 80 d B.在正常使用程范围内,显示值和实际输出最大误差小于 0 .0 5 V.系统具有输出内阻低、功耗低、通用性好、可靠性高、线路简单、成本低廉、使用直观方便的优点 .
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.
