Unmanned helicopter starting and power supply integrated power supply control system and method

Abstract

The invention discloses an unmanned helicopter starting and power supply integrated power supply control system and method. The system comprises a brushless direct-current generator, a full-bridge LLCresonant conversion circuit, a storage battery pack, a DC / DC bidirectional buck-boost circuit, a starting motor and a detection and conditioning circuit. One end of the full-bridge LLC resonant conversion circuit is connected with the generator, and the other end of the full-bridge LLC resonant conversion circuit is connected with a direct-current bus; the brushless direct current generator is connected with a turbine engine of an unmanned helicopter; one end of the DC / DC bidirectional buck-boost circuit is connected with the storage battery pack, and the other end of the DC / DC bidirectionalbuck-boost circuit is connected with the direct-current bus; a starting motor is electrically connected between the DC / DC bidirectional buck-boost circuit and the storage battery pack; the full-bridgeLLC resonant conversion circuit, the DC / DC bidirectional buck-boost circuit and the storage battery pack are connected with the input end of the detection and conditioning circuit; and the starting motor is connected with the turbine engine through a gear. According to the invention, the power supply range of the generator is improved, the complete fault diagnosis and protection functions are realized, 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.
