The invention discloses a control device for a helicopter AC power supply system, comprising a master control signal generation circuit, a stable control circuit, a fault protection circuit, and a power supply circuit. The main control signal generation circuit is used for sampling AC high voltage signals outputted by a helicopter AC power supply system and performs follow-up processing to obtain a master control signal of the stable state control circuit; the stable state control circuit is used for receiving a control signal and presetting a reference signal, performing comparison and outputting an exciting current control signal to an AC motor of the helicopter AC power supply system according to the comparison result; the fault protection circuit is used for sampling a fault signal of the helicopter AC power supply system and determining a fault state of the helicopter AC power supply system; the power supply circuit is used for supplying power to the control device. The stable state control circuit is high in control accuracy, fast in responding speed, can fast respond to stable state control when a load abruptly changes. The fault protection circuit samples the fault signal of the helicopter AC power supply system and determines a fault state of the helicopter AC power supply system, and thus the working reliability of the helicopter AC power supply system is improved.
Description
technical field [0001] The invention relates to the field of helicopter electronic accessories, in particular to a control device for a helicopter AC power supply system. Background technique [0002] Helicopter AC power system is generally composed of AC motor, control device and current transformer, which outputs AC power to the helicopter power grid for use by airborne equipment. Among them, the control device is the core control component of the AC power system. Due to the complex load conditions of the helicopter's AC power system, the control device must quickly respond to changes in external signals, so that the AC power system can have high power supply stability and reliability under complex conditions. At the same time, the control device should be equipped with a complete fault protection mechanism. When the AC power system itself or the electrical equipment fails, the control device will detect the fault and issue a fault indication. [0003] The existing contr...
