The paper presents the design of three-level variable-frequency power supply device which is used in electric propulsion system of ship The variable-frequency power supply device is controlled by the DSP chip TMS320LF2407, and inverter is neutral point clamped three-level inverter circuit which is consisted by IGBT, and it’s controlled by SVPWM modulator approach to determine switching elements making or breaking. In order to keep the balance of neutral voltage, the paper presents to use the method that two equivalent switch state of short vector work alternatively to cut down the variable quantity of capacitive, and to achieve the voltage balance. Rotor flux orientation vector control of torque closed loop control has taken in the speed control system of propulsion motor. The whole variable-frequency power supply device has some strong points such as working reliably, dynamic response fastly, current ripple small and less harmonic content of output voltage, etc, it has some practical value.
