Abstract: Single stage switching power supply with half bridge topology simulation for LED lamp Driver is presented in this paper. LED lamp driver needs only dc supply. In this paper dc supply is obtained as output while giving ac input voltage of 110V. It is formed by combination of ac/dc converter and dc/dc post regulator. Compared to other switching power supply this reduces cost ,size and simplifies circuit design. It increases efficiency and output voltage can be controlled. The simulation of single stage switching power supply using half bridge topology using Psim software is done and output voltage and power are verified .by using this get an output voltage of 48 V dc output and power range up to 120 W ,and efficiency is above .89 . It is used in LED lamp drivers and piezoelectric element drivers.
