Single-Phase Mains Fed Three-Phase Induction Motor Drive Using Improved Power Quality Direct AC–AC Converter

This article presents an alternative ac–ac converter topology and its control for low-speed three-phase induction motor drives fed from single-phase ac mains. The proposed matrix based drive system eliminates the dc link capacitor, thus facilitating high power density reliability. primary challenge in controlling a $1\phi$ to notation="LaTeX">$3\phi$ is navigate discrepancy of instantaneous across grid load via direct converter. In order address this concern, it use mathematical modeling input LC filter state selection, deliver improved current waveforms. Enhanced performance demonstrated through simulations, further validated using experimental results. Particularly quality achieved at low speeds, where precise sensorless operation ensured suitable speed observer.
