POWER CONVERSION APPARATUS

摘要

A power conversion apparatus, including a transformer, a switch, an analog controller, a digital controller, and a voltage converter-based feedback circuit, is provided. The primary side of the transformer is coupled to an input voltage, and the secondary side of the transformer is coupled to an output voltage provided to a load. The switch intermittently transmits the input voltage to the primary side of the transformer. The analog controller is disposed at one of the primary side and the secondary side of the transformer and configured to control the operation of the switch in response to an analog feedback signal. The digital controller is disposed at the other one of the primary side and the secondary side and configured to generate a digital feedback signal. The voltage converter-based feedback circuit is configured to convert the digital feedback signal to the analog feedback signal based on a voltage conversion characteristic thereof.
