摘要: | The proposed current-mode synthetic control (CSC) technique in the design of boost converters can improve the transient response time and maintain high conversion efficiency over a wide load range. The CSC technique has high accuracy similar to the current-mode control and doesn't need the slope compensation for simplicity. Besides, the transient response is also improved due to the current-mode hysteresis control. The load-dependent switching frequency at light loads results in high power conversion efficiency. Experimental results show that the output voltage ripple can be kept smaller than 50mV over a wide load current range from 0mA to 400mA with power conversion efficiency higher than 90% at load current of 10mA. |
