The rapid advancement and development in the field of power electronictechnologies comes up with a lot of power electronic related productssuch as Switch-Mode Power Supply, Uninterruptible Power Sullpy, DC-to-DCConverter etc. Each of these equipment utilizes the power switching deviceslike power Bipolar adn Power MOSFET. Power or energy losses during the switching intervals decrease the efficiency of this products.In order to increase the equipment's efficiency, the energy losses of theswitching devices during the switching intervlas must be reduced and in turn recovered back to the supply rail or load.In order to increase the equipment's efficiency, the energy losses of the switching devices during the switching intervals must be reduced and inturn recovered back to the supply rail or load.Owing to the above problem, the research of the Energy Recovery SnubberCircuit is carried out. This energy recovery snubber circuit is based onthe technique of Passive Energy Recovery which utilizes the passivecomponents like capacitor, inductor and diode to perform the functionof energy recovery. The dissipative components like resistor dn zenerdiode are not included to avoid the energy dissipation.The passive Energy Recovery Snubber has been studied for Power Transistorand Power MOSFET with different resistive and the combination resistive-inductive load, by using Pspice si,ulation. The results of these study shows that the amount of enery recovered for Power Transistor is more than 80% and almost 100% for Power MOSFET.
