摘要
提出了一种开关型精密校验电源系统的实现方法,应用该方法研制的试验电源其输出精度达0.2%,输出相位、频率调节细度为0.01°和0.01Hz,完全满足系统应用要求。
A implement method of a switch-mode precise power supply for verifying is proposed in the paper.The output precision of the power supply for testing is 0.2%,and modulation degree of the output phase can reach 0.01 and modulation degree of frequency can reach 0.01Hz. So it completely fulfills the demand of the system.
