Abstract: This study presented a Zeta converter based on Model Predictive Controller (MPC), this converter consist of high frequency transformer on the primary side and two diodes and two switches for welding application. This proposed converter is operated in DCM discontinuous inductor current mode and dynamic performance using this method result is reduced switch stress and also this converter provides constant output voltage to maintain, easy to control, hence, only one gating signal is used to drive both the switches. Using MPC controller, the proposed converter gives good efficiency, lower Total Harmonic Distortion (THD) and power factor correction at the utility.
