In this thesis, a non-isolated buck-type converter, together with half resonance and zero voltage transition to achieve zero current switching and zero voltage switching, is presented, in which the source terminal of the MOSFET switch is connected to the ground so as to make this switch easy to drive. In addition, the pulse width modulation (PWM) control technique is utilized in this converter so as to render the required output filter easy to design. By doing so, the problems in the electromagnetic interference (EMI) and power dissipation are reduced and hence the efficiency of this converter is upgraded. In this thesis, the theoretical derivation is firstly introduced, and secondly the simulated and experimental results are provided to demonstrate the effectiveness of the proposed topology.
