Description
Summary:This paper presents a single-phase to three-phase adjustable-speed drive (ASD) system, which consists of a diode rectifier and a single-stage boost inverter without electrolytic capacitors (E-caps). The system has no shoot-through issues and gains high reliability due to the shoot-through zero-state regulation method. By using electrolytic capacitors-less topology, the lifetime can be greatly increased. By properly designing the tapping position of the inductor, the system has a high boost-inversion gain and can ride through grid voltage sags. By using the proposed harmonic injection method, the system can realize high input power factor and small dc-link ripple voltage, simultaneously. Experimental results of the electrolytic capacitors-less single-stage boost inverter (E-caps-less SSBI) based single-phase to three-phase ASD system are obtained to verify the actual performances.
