| Summary: | Aiming to the problems existing in the excitation voltage adjustment system of aircraft power support van such as slow dynamic response speed and the poor output voltage stability, it proposes a scheme of introducing DC supply control to the excitation voltage adjustment system in order to form a double closed loop control system. For eliminating the unstable stability of switch frequency in hysteresis current control method which may cause high harmonics of output voltage and easy-damage of power switch devices, it also proposes a scheme of variable loop width and constant frequency hysteresis current control to keep high speed response and constant switch frequency. Results of simulation and test show feasibility of the introduced scheme. |
