摘要：

The self-oscillating flyback converter is a popular circuit for cost-sensitive applications due to its simplicity and low component count. It is widely employed its mobile phone chargers and as the stand-by power source in off-line power supplies for data-processing equipment. However, the optimization of this circuit is almost exclusively performed by a cut-and-try approach since its operation is generally not well understood. This paper presents a detailed steady-state analysis of the self-oscillating flyback converter along with its small-signal model. Design guidelines of the control circuit and loop compensation are presented and verified oil all off-line, stand-by, 5-V/2-A power supply.
