Research on synchronous speed of voltage-controlled inverter

This paper proposes a synchronization control strategy based on voltage-controlled inverter and the synchronous speed is controllable. The proposed inverter can be simplified as a circuit consists of a controlled voltage source and equivalent impedance, the output voltage amplitude and frequency can be changed by adjusting the axial-regulators. The designed synchronization method has detection module and regulation module to regulate the synchronous speed. As impulse current and harmonic contents have relationships with the synchronous speed, this paper would analysis the relationships and find a suitable range of the speed.
