This paper describes about a performance analysis of Modified Quadratic Boost Converter for switching and conduction loss. Modified Quadratic Boost Converter has single active switch with control strategy. MQBC eliminates the requirement of additional driver circuit and improves the output voltage. High voltage gain was the main advantage of MQBC. The circuit was simulated in PSIM software for both open loop and closed loop by using ideal MOSFET switch. The PID controller is used as a feedback loop to attain the faster stability. The switching and conduction losses are estimated by considering a thermal module of MOSFET in PSIM and compare it with the ideal MOSFET switch. These losses are estimated even for the diodes. The characteristics of N-Channel Power MOSFET IRFP460 are nanosecond switching speed with the 20A, 500V rating specifications. The specifications present in IRFP460 MOSFET data sheet are added to PSIM software by using device database editor. The design specification of proposed converter is Vin = 24V, Vo= 92V and P= 40W. The comparative simulation of ideal switch of MOSFET with the thermal module of IRFP460 includes a power value of 20A, 500V, 0.270 Ohm, N-Channel Power MOSFET are analyzed. The converter gain of 60% and designed values of inductors, capacitors and resistance are 71.28 uH, 288uH, 11.57 uF, and 230ohm respectively. The open loop and closed loop simulation results of transistor conduction losses and transistor switching losses are 9.059W, 9.02W, 6.08W, 5.42W respectively.In this proposed paper the switching and conduction losses of both the transistor and the diodes of the Modified Quadratic Boost Converter by using the PSIM software tool.
