Abstract
This paper deals with a new method for very high static gain for DC-DC converter based on the modified SEPIC converter. The main improvement is low switch voltage with higher efficiency can be achieved by using magnetic coupling and output diode clamping. Without increase the switch voltage static gain can be increased by using magnetic coupling and voltage multiplier. Voltage multiplier at the secondary side will reduce the overvoltage across output diode. Simulation result show that proposed SEPIC converter suitable for low input and high output applications. This method improve the load regulation. The overall circuit produce 94% efficiency with an output voltage equal to 300V.
