A DC-DC Converter for Electric Vehicle Application

An innovative Synchronous Buck Converter (SBC) with a wide input voltage range is presented in this article for use in Electric Vehicle (EV) applications. The disadvantages of higher losses in an Asynchronous Buck Converter (ABC) are intended to be addressed by the Synchronous Buck Converter. Fewer losses occur in the circuit when MOSFET (or any controlled switch) is used in place of diode. To enhance system performance, a control approach known as Emulated Peak Current Mode (EPCM) is employed. The design of a broad range input SBC and the investigation of power loss calculations using different control techniques, which are implemented using PSIM, are the primary contributions made in this paper. The buck converter employed in this paper has an output voltage of 12 V and a wider input voltage range of 40–75 V. It is utilized by electric vehicles' light and horn systems. Using PSIM software, the SBC using the EPCM, Current Mode Control (CMC), and Voltage Mode Control (VMC) techniques is simulated. Hardware results coincide with the simulation results and thus the results are validated.
