Abstract :
This paper summarizes current designs of power supplies (PSs) for industrial drives and presents a novel universal switch-mode power supply (SMPS) approach. Adjustments to the switching algorithm and transformer turns ratio are presented to improve ride-through characteristics and allow the SMPS to operate as a universal supply over a wide input voltage range, without the additional circuitry of current universal PS systems. The proposed approach can also overcome potential safety issues of common universal PSs and is equally suitable to meet the requirements of many commercial systems. Simulation and experimental results on a 100 W (5 V/20 A) halfbridge SNIPS are provided to demonstrate the proposed approach.
