A high step-up DC-to-DC converter that integrates an isolated transformer and a switched-clamp capacitor is presented in this study. The voltage stress of the main power switch should be clamped to 1/4 V by using the turn ratio and switched-clamp capacitor of an isolated transformer to achieve a high voltage gain. In addition, a passive clamp circuit is employed reduce voltage stress on the mai...

the monolithic catalytic converter is still the main pollution control device for modern vehicles in order to reach the ever-increasing legislative demands for low emission standards. the catalytic converters require a large expansion from the exhaust pipe to the front face of the monolith. unfortunately, packaging constraints often do not permit the use of long diffusers. hence, flow separatio...

A high frequency, low voltage, high current DC-DC converter is most suitable for high speed electronic circuits like microprocessors, telecommunication networks etc. This paper presents the details regarding the selection of Isolated DC-DC converter for high current applications using Current Double Rectifier (CDR) among four isolated DC-DC Converters such as flyback, forward, push-pull and two...

The comparision of bridgeless isolated cuk converter using proportional integral derivative (PID) and neural controller (NC) is presented in this paper. Due to diode bridge rectifier (DBR) conventional converters suffer from high conduction loss. Bridgeless Cuk converter is used to eliminate the issues. bridgeless isolated (BLI) cuk converter is used to withstand high voltage. Compare to Contin...

This paper suggests an isolated dc/dc converter using an unregulated LLC converter for fuel cell applications. The LLC converter operates as an isolated voltage amplifier with a constant voltage gain, and a nonisolated converter installed in the input stage regulates the output voltage under a wide variation of fuel cell stack voltage. By separating the functions, the unregulated LLC converter ...
