摘要
设计一电力节电器,由双向交流BUCK斩波器与变压器串联组成。该串联型的电力变换器采用ATmega128来产生PWM开关信号和完成整个电路的电压闭环智能控制;新颖的PWM开关驱动方式使得此节电器可适用于任何负载,且节电效果明显。实验结果表明此节电器的节电率可达30%。
The development power saver consists of a series connected power transformer and a bi-directional AC chopper.Since a series regulated power converter needs only to transfer a fraction of the total power supplied to the load,its efficiency is very high.An AVR microcontroller was adopted to generate the PWM waveforms controlling the AC chopper and to complete the intelligent voltage closed-loop control.As a novel PWM scheme was adopted,the power saver is versatile to many kinds of loads and can save electric power remarkably.Experiment result shows that its power saving rate can be up to 30%.
