Abstract: A novel high voltage direct current power system suitable for the airplane consisting of PMSG(permanent magnet synchronous generator), PWM(pulse width modulation) rectifier and controller based on SVPWM(space vector pulse width modulation) was proposed. The system had many advantages such as simple structure and high reliability. It can not only guarantee that the input current was sine wave, but also can still output stable high voltage direct current while the speed of the airplane or the load changed. Then the system was simulated, the results of the simulation were in line with the theory analysis.
