Product Description

On Grid Generator Power System

Off Grid Generator Power System

The on grid generator converter adopts AC-DC-AC PWM rectification plus PWM full-bridge inverter two-stage circuit technology. The core control adopts dual DSP full digital control, and realizes the stator magnetic field oriented vector control strategy on the rotor side converter of power generation. The grid-side converter implements the grid voltage directional vector control strategy; the system has the functions of adjustable input and output power factor, automatic soft grid connection and maximum power point tracking control. The power module uses high switching frequency IGBT power devices to ensure a good output waveform. This rectifier inverter device has the advantages of simple structure and less harmonic content.
