Abstract
This paper presents a current fed full bridge boost DC/AC/DC converter with transformer isolation. However, Higher frequencies result in the increase of transistor switching losses, and thus, the converter's effectiveness is limited. For this reason, to minimize the converter switching losses this converter with transformer isolation operating without switching power dissipation has been implemented. In the proposed scheme, PIC16F72 controller is used to produce signals. An universal motor of 150W, 30V-90V, 1.6A-5A rating and a resistive load(incandescent lamp with different watts) are used as load for testing the developed hardware. Textronics TDS2024B storage oscilloscope is used to store the gate pulses and waveforms. Keywords: MOSFETs, Bridge, Universal motor, DC/DCAC/DC converter, Resonant tank.
