一种用于恒定突发频率且消除可听噪声的突发模式变换器抛物线电压控制策略

To improve the conversion efficiency at light load, burst mode control is widely employed by power converters. One drawback of hysteresis burst mode control is that the burst frequency changes with different load, which would introduce audible noise to the system if burst frequency falls into audible frequency range. To solve the frequency variation and audible noise problems of burst-mode-control...
