Emulated Peak Current Control of an Integrated Buck Converter for Automotive Applications

This thesis presents the analysis and simulation of an innovative current control system for DC-DC buck converters, based on inductor current emulation rather than direct measurement. This approach is motivated by the increasing demand for power conversion solutions in automotive applications, where high switching frequencies and wide conversion ratios are often required. The proposed method replaces the conventional current sensing circuit, simplifying the overall system architecture. The control strategy has been developed and validated through simulations, confirming the viability of current emulation.
