Design and Implementation of an SMPS for UPS Charging and Discharging System using the DC-DC buck converter method by Kim dong-Rok Department of Electronics & Mechatronics Engineering Graduate School of Industrial Technology and Management Korea Polytechnic University
The purpose of this paper is to develop the SMPS(Switched Mode Power Supply) for the implementation of the charge-discharge system of the UPS(Uninterruptible Power System) with the DC-DC buck converter. The proposed SMPS is designed to be able to switch two different output voltage levels and it has provided a circuit configuration for the two output voltage. This SMPS operated the generator circuit of the output voltage in response to the state of the High/Low of the output selected signal. As the rest of the circuit groups are not driven, unnecessary power consumption is minimized. The equipment with a high battery power is possible to charge by using the 2 fuse-2 outlet cable on the 12~70V DC area. The equipment with a low battery power is possible to charge by using the 8Fuse-8prong cable on the 12V DC area. Eventually, the developed SMPS system is capable of controlling by a simple switch as well as efficient.
