Abstract
This paper proposes a zero-voltage transition in a boost converter. The presence of adaptive mechanism provides significant reduction in the converter volume, since the multiple switches is replaced by variable frequency operation with a single switch. Also, the semiconductor elements benefit from soft-switching conditions and thus, high efficiency is achieved to maintain continuity of supply. The other properties of the proposed system include no extra voltage and current stresses on the main switches and the ease of control. The proposed technique is fully analyzed for a boost converter and the reliability is achieved by Matlab simulation. The simulation result proves that a successful set point value of 60V gives an accurate output voltage with input voltage of 40V. Index Terms - DC-DC converter, Pulse-Width Modulation (PWM), ZVS (Zero-Voltage Switching), Adaptive Mechanism.
