  • Control method for series hybrid power system or synergic electric power supply and control device thereof
    Patent number: 10807498
    Abstract: A control method for a series hybrid power system or synergic electric power supply and a control device thereof are disclosed. The control device includes: a generator reference current value generating module and a generator current control module. The generator reference current value generating module is configured to generate a reference current value of a generator according to an actual current value of an energy storage device, a reference current value of the energy storage device, an actual voltage value of a DC bus, and a reference voltage value of the DC bus. The generator current control module is configured to generate a control signal of a rectifier according to the reference current value of the generator, the actual value of any two-phase current of the generator, and an actual angular velocity of the generator, thereby controlling the series hybrid power system or the synergic electric power supply.
