| description | The invention discloses a power supply circuit and an output control method thereof. The power supply circuit comprises a power conversion module, an isolation sampling module, a first control module and a second control module, the output control method comprises the steps that the isolation sampling module collects the output voltage of the power conversion module and converts the output voltage into a first sampling voltage; the second control module collects the output voltage and converts the output voltage into a second sampling voltage; the first control module converts the first sampling voltage into a digital quantity signal, adjusts the digital quantity signal according to the second sampling voltage, and controls the output of the power conversion module according to the adjusted digital quantity signal. According to the embodiment of the invention, the problem that the voltage regulation direction deviates from the expectation due to characteristic deviation of internal devices of the isolation sa |
