This study presents the simulation of a Type-E chopper (single-quadrant MOSFET-based DC–DC converter) using MATLAB/Simulink to evaluate its dynamic and steady-state performance under practical operating conditions. The developed model includes a power MOSFET switch, freewheeling diode, input source, filter inductor and capacitor, and resistive as well as variable loads. The effects of duty cycle, switching frequency, and load variation are analyzed in terms of output voltage regulation, current and voltage waveforms, ripple content, and switching and conduction losses. Key performance metrics such as conversion efficiency, transient response, and RMS and peak inductor currents are evaluated. The results demonstrate that duty-cycle control effectively achieves the desired output voltage, reveal the trade-offs between switching frequency, ripple, and efficiency, and guide component selection and gate-drive timing in low-voltage, high-efficiency applications.
