    摘要: The prevent invention provides an AC-DC flyback converter and a loop compensation method thereof. The AD-DC flyback converter comprises an isolating transformer, a power switch, and a feed control module. The feed control module includes a compensating circuit, a voltage buffer, and an error amplifier having a first resistor and a second resistor, and a pulse width modulation controller. With the AC-DC flyback converter and the loop compensating method, the system stability can be improved and the loop bandwidth can be reduced.
