A NOVEL SINGLE SWITCH HIGH STEP UP DC-DC CONVERTER FOR PV BASED APPLICATION

Arunkumari T, Indragandhi V

Abstract


A new converter of single switch mode with high step up ratio is proposed in this manuscript. The proposed converter design is a combination of Voltage Tripler (VT) and sepic boost converter. This design uses MOSFET switch with reduced switching and conduction loss.  Converter achieves high step up voltage gain with appropriate duty cycle and less voltage strain on the switch. The energy stored in the inductor can be recycled towards the output capacitor. The working condition of the converter under Continuous Conduction Mode (CCM) is given in detail. The input of 30V of PV source is boosted to 400V by this proposed converter. The main advantage of the proposed converter is single switch, reduced component stress and size, the ripple current and voltage is less. The efficiency attained is 93%. The simulation of this converter is done using MATLAB Simulink.

Keywords


Boost converter, CCM, high voltage gain, Single switch, voltage Tripler.
