Abstract

In this paper, an implementation of a DC/DC buck converter for electric vehicles charging station and a DSP based closed-loop digital controller design are presented and analyzed. The aim of this work is to achieve an improved control strategy for a Li-ion battery charger implemented on a Real-time test platform. The test platform consists of a popular power pole board (MPCA75136) dedicated to studying the DC/DC converters, and a DSP development kit (TMS320F28379D) that is used to drive the DC/DC buck converter. The control strategy is based on a digital control system containing the closed-loop current controller followed by a pulse width modulation block, and on a real time state of charge estimation technique for a Li-ion battery. However, the overall control design is modeled on Simulink via block diagrams, and automatically generated code that is targeted into the DSP processor. Simulation and experimental results have shown the effectiveness of the proposed test bench and its external digital control strategy via a charging scenario for electric vehicles batteries.

Abstract

This paper presents a simulation and comparison of direct power control (DPC) and the new backstepping (BS) control for a three-phase PWM rectifier. The objective is to evaluate these techniques in achieving high-performance grid integration, targeting the absorption of sinusoidal current, maintaining a unity power factor, and minimizing grid current harmonics. While DPC is recognized for its fast dynamic response, it often suffers from high power ripples and variable switching frequency due to the switching table. Conversely, the proposed BS control provides superior tracking performance and improved stability margin, even under parameter uncertainties. Through detailed modeling and simulation in MATLAB/ Simulink environment, this paper analyzes key performance indicators, including current total harmonic distortion (THD), response time, and robustness, under multiple grid conditions, and validates the proposed control law using a processor-in-the-loop (PIL) implementation. The comparative study demonstrates the trade-offs between the two control methods, highlighting the advantage of backstepping control.
