Abstract: This column elucidates analysis and design of novel single switch non-isolated quadratic boost converter. The operating principle is discussed both in CCM and DCM mode. Analysis includes closed loop average current mode control. The proposed converter exhibits stable operation under input voltage and load change. Linear control theory is applied for the loop compensator design. The suitability of the proposed scheme is well visualised and validated through simulation results procured using PSIM 9.1.1 and experimental results obtained from a practical 75 watt converter. The converter is designed for 75 watts with 89%-90% measured efficiency, where voltage and current ripple is 2% of output voltage and 1% of rated inductor current, respectively.

Keywords: quadratic boost converter; CCM mode; DCM mode; voltage stress; voltage step-up ratio; current mode control; efficiency.
