Abstract
This paper presents an improved ZVT(Zero Voltage Transition) DC/DC Boost Converter using Active Snubber. The Conventional ZVT PWM Boost Converter is improved to minimize the switching loss of auxiliary switch using the minimum number of the components. In this thesis, advantage and disadvantages of Conventional ZVT Converter using a auxiliary resonant circuit is discussed. Then Improved ZVT soft switching converter will be discussed. In comparison a previous ZVT converter, The proposed converter reduces turn-off switching loss of the auxiliary switch Therefore, the proposed converter has a high efficiency by active snubber. The prototype of 100kHz, 2kW system was implemented to show the improved performance.
