Abstract :

The paper will focus on modeling, analysis, and design and simulation buck converter architecture. This architecture is used for automotive dual power system to reduce filters, dynamic response and power. The converter is designed in CCM (continuous conduction mode). The voltage mode control strategy is proposed by using pulse width modulation (PWM) with a proportional–integral–derivative (PID). The effectiveness of the step down converter is verified through simulation results using control oriented simulator like MATLAB/Simulink tools. The proposed circuits operate at constant frequency and are regulated by conventional pulse width modulation (PWM) using dedicated PWM and PID control techniques. The circuit operation, mathematical analysis, designs and simulation results for continuous current mode (CCM) operation are mentioned in this paper.
