摘要
利用调宽式稳压电源与调频式稳压电源在连续可调范围内的互补性，采取混合调制方式扩展了变换器型稳压电源的连续可调范围．实验结果表明，可使２０Ｖ／１２５Ａ直流开关稳压电源的电压调节范围扩大１８％
A scheme is put forward to enlarge the continuously adjustable range of a voltage stabilized source of transformer type by using a mixed mode of modulation combining the width modulation with the frequency one.Which makes reasonable use of the complementarity in the continuously adjustable range between the width modulated voltage stabilized source and the frequency modulated one.It has experimentally proved that the continuously adjustable range of a voltage stabilized source with a direct current switch of 20V/125A made on that bases can be enlarged by 18per cent.
