Abstract

The invention discloses an integrated power supply control system and method for unmanned helicopter startup and power supply. The system includes a brushless DC generator, a full-bridge LLC resonant conversion circuit, a battery pack, a DC / DC bidirectional buck-boost circuit, and a starter motor. and detection and conditioning circuit; one end of the full-bridge LLC resonant conversion circuit is connected to the generator, and the other end is connected to the DC bus; the brushless DC generator is connected to the turbine engine of the unmanned helicopter; the DC / DC bidirectional One end of the buck-boost circuit is connected to the battery pack, and the other end is connected to the DC bus; the DC / DC bidirectional buck-boost circuit and the battery pack are electrically connected to the starter motor; the full-bridge LLC resonant conversion circuit, DC / DC Both the bidirectional buck-boost circuit and the battery pack are connected to the input end of the detection and conditioning circuit; the starter motor is connected to the turbine engine through gears. The invention improves the power supply range of the generator, has perfect fault diagnosis and protection functions, and the system has high reliability.

Description

technical field [0001] The invention relates to an integrated power supply control system and method for unmanned helicopter startup and power supply, and belongs to the technical field of unmanned helicopter power supply control. Background technique [0002] Unmanned helicopter has unique flight performance and use value. It has the characteristics of no casualties, small size, low cost, strong battlefield survivability, flexible flight, strong survivability, and strong airport adaptability. Helicopters are widely used in both military and civilian applications. On the military side, unmanned helicopters can perform various non-lethal tasks as well as soft and hard lethal tasks; on the civilian side, unmanned helicopters are used in atmospheric monitoring, traffic monitoring, resource exploration, power line detection, forest fire prevention etc. The unmanned helicopter generally supplies power to the starter motor through the battery to drive the turbine engine of the u...
