摘要：
A novel Space Vector Pulse Width Modulation (SVPWM) control strategy added feedforward link used for wide input voltage range inverter is proposed. The input voltage is sampled in real time and the sampled values are taken into account, and thus a quick response to the change of input voltage can be achieved. Different form previous researches, the modified SVPWM control strategy presented in this paper is simple and easy to implement without any extra complexity of inverter topology and without switching between different control modes. This method has been applied in the five-level Neutral Point Clamped (NPC) inverter with high frequency link, and the simulation model with 80 similar to 780VDC input, 320VAC output, and the THD of output voltage less than 2% is established using the software Power Simulation (PSIM). The THD of output voltage are all less than 2% no matter the input voltage varies or stays at anywhere among this range. The feasibility and effectiveness of the modified SVPWM control strategies proposed are well verified by the simulation results.
