一种在极端轻载下具有噪声抑制能力的LLC谐振变换器双脉冲开关模式

LLC resonant converters are widely used in wide power range applications. However, their switching frequency will be much higher than normal load when they are applied under extreme light load conditions. Therefore, burst mode control is introduced to reduce the high switching loss and increase the light load efficiency. By applying the trajectory theory, a three-pulse switching pattern is impleme...
