摘要：The VSCF squirrel-cage generation system mostly adopt full power double pulse width AC/DC/AC modulation. In order to reduce the capacity of the rectifier, a rectification system and its voltage control strategy is proposed. The rectifier and capacitor in parallel with the generator are used to compensate the excitation current and to adjust the generator voltage. Uncontrolled rectifier bridge and inverter are connected to the generator to supply electricity for the AC loads. The selection of build-up voltage capacitor is analyzed and system voltage control method is simulated and experimented. The rectification voltage can be kept basically a constant when the rotor speed and load change in a certain range. The rectifier compensating current is small which proves that the system structure is feasible and control method is effective.
