Modified Two-Stage Interleaved Boost Converter (MTSIBC) For Electric Vehicle Application

Abstract

This paper, to extract maximum power from the source, controllers like Maximum Power Point Tracking (MPPT) are used in circuits. This circuit uses Modified Two-Stage Interleaved Boost Converters (MTSIBCs), which link power from the solar photo voltaic system to the load. An Interleaved Boost Converter is modified and the design of a modified Two-Stage Interleaved Boost Converter (MTSIBC) is discussed. The Converter is an essential part of an e-vehicle. To improve the performance of the converter, an Interleaved Boost Converter is modified.A PWM method is used to generate pulses for the MOSFET in the MTSIBC. To boost the output voltage, the boost converter uses a single switch for ON and OFF. This will increase the stress on the switch thereby affecting the performance of the converter. To reduce the strain on the switches, a two-stage 180⁰ phase shifting technique is implemented in MTSIBC. The stress on the switches is reduced by applying the interleaved technique. Overall losses have been mitigated by using the phase-shifting technique. A PV-based MTSIBC and two-stage interleaved boost converter (TSIBC) with a DC motor load are simulated with 31 kHz switching frequency. The efficiency of the MTSIBC is 4.36% higher than TSIBC efficiency.
