HBC-Based 3Ø System for Wide Range of Power Conversion

The significance of this research work is the hidden bidirectional chopper (HBC) in three-phase systems for the production of a wide range of voltages. Modes of operation in the electrical system ensure productivity and quality, so the proposed system requires four modes of operation. Four modes of approaches are buck rectification, boost inversion, direct rectification, and direct inversion: the first two modes of operation are two-step conversion processes with HBC, where direct inversion and rectification modes exclude HBC for the single-stage operation. HBC is controlled by the standard PI controller to establish output on both sides as a perpetual and three-phase inverter with horizontal switches controlled by the carrier-based pulse width modulation (CBPWM) technique. The system is intended to use quantitative models and initially evaluated on the Simulink platform in MATLAB. Simulation results are validated using a real-time test bench model.
