This paper contains a high voltage gain non isolated dc-dc converter having coupled inductor and diode-capacitor techniques. The converter have large voltage conversion ratio with appropriate duty cycle. The energy present in leakage inductance of coupled inductor is recycled to the output efficiently. The voltage stress on the switch is reduced. This paper proposes simulation and hardware implementation of a pv fed high voltage gain dc-dc converter with coupled inductor.

“…Many bidirectional DC-DC converters have been researched. The bidirectional DC-DC flyback converters are more attractive due to simple structure and easy control [2], [16], [17]. However, these converters suffer from high voltage stresses on the power devices due to the leakage inductor energy of the transformer.…”

This work deals with reduction of ripple in the bidirectional DC-DC converter. This Converter has the ability to transfer the energy in both the directions. This converter is designed, modeled and simulated using MATLAB SIMULINK and the results are presented. The Pi-filter is proposed at the output to reduce the peak to peak ripple. The simulation results with R-load and DC-Motor load are presented.

“…However, the power switches may not be triggered at the same instant so that the actual voltage stress of power switch is greater than V in /2 under two switches. Reference [6] presents a series-connected flyback converter to reduce the voltage stress. However, the voltage stress of power MOSFETs is still higher than V in /2.…”

This paper presents a new DC/DC converter for high input voltage and high load current applications. In order to adopt low voltage rating power devices in high voltage applications, two split capacitors with four active switches are used in the primary side to reduce the voltage stress of power switches at V in /2. Two flying capacitances are used in order to automatically balance two split capacitor voltages in every switching cycle. The proposed converter includes two resonant circuits to share the load current and to reduce the current stress of passive components. If the switching frequency is less than the series resonant frequency, power switches can be turned on under zero voltage switching and rectifier diodes can be turned off under zero current switching. Therefore, the switching losses on power semiconductors are reduced. The interleaved pulsewidth modulation is adopted to further reduce the ripple current at output side. Thus, the output filter inductances can be reduced. Finally, experiments with a 1.2kW prototype are provided to verify the effectiveness of the proposed converter.
