This project involves the design and simulation of a boost converter, a type of power electronics circuit used to increase the voltage of a DC power source. The design process includes selecting appropriate components such as the inductor, capacitor, and switch, as well as determining the optimal operating conditions.
The simulation is performed using LTspice and Simulink to analyze the behavior of the circuit under different load conditions. For controlling the circuits voltage and current levels, the chosen components are a Si-FET transistor and five SiC-diodes. The chosen capacitors is one 10 mF 350 V electrolytic capacitor and a 12 µF 500V fast-switching solder pin capacitor. The inductor is designed to have an inductance of 874µF. The circuit’s duty cycle is controlled with a PI-regulator, with the values Kp = 0.3, Ki = 40. The calculated efficiency is 99%.
