单端反激式开关电源具有结构简单、输入输出电气隔离、电压升/降范围宽、易于多路输出、可靠性高、造价低等优点,广泛应用于小功率场合。然而,由于漏感影响,反激变换器功率开关管关断时将引起电压尖峰,必须用钳位电路加以抑制。由于RCD钳位电路比有源钳位电路更简洁且易实现,因而在小功率变换场合RCD钳位更有实用价值。 -Single-ended flyback switching power supply with a simple structure, input and output electrical isolation, voltage up/down range, easy to multi-output, high reliability and low cost, widely used in low-power occasions. However, due to leakage effects flyback converter power switch off when the voltage spike caused by the need to be inhibited by clamping circuit. RCD clamp circuit as a result of active-clamp circuit than the more concise and easy to realize, and in low-power transform RCD clamp occasions more practical value.
