一种基于线缆与电感补偿方案的高精度恒压/恒流AC-DC变换器

This paper proposes a high-precision primary-side regulation constant voltage (CV) and constant current (CC) ac–dc converter. CV output is achieved by adjusting the switching frequency and primary peak voltage simultaneously, for better dynamic adjustment ability. In order to improve CV precision, a cable compensation module is adopted to inject current to pull-down resistor of auxiliary winding d...
