| description |
This paper presents a single-phase to three-phase AC-DC-AC step-down converter with a symmetrical DC-link voltage ratio. The proposed converter architecture is well-suited for rural distribution grid applications, where a high-voltage single-phase grid is required to transmit energy over long distances while minimizing conduction losses. The converter consists of two cascaded H-bridge converters connected via transformers and two three-phase inverters supplying an open-end winding induction motor (OEWIM). The level-shifted pulse-width modulation (LSPWM) strategy is employed to synthesize the converter voltages. A proportional-integral (PI) controller regulates the overall DC-link voltages, while a hysteresis controller maintains the balance of the individual DC-link voltages. Additionally, a resonant PI controller ensures a sinusoidal grid current, and a Phase-Locked Loop (PLL) is used to achieve a high power factor in the grid. Compared to a conventional two-level leg topology, the proposed configuration reduces harmonic distortion and semiconductor power losses while ensuring a high power factor.
Simulation and experimental results validate the effectiveness of the PWM and control strategies.
