Modularized large-current parallel starting and generating integrated controller and control method

Abstract

The invention discloses a modular large-current parallel starting and generating integrated controller and a control method, and belongs to the field of starting and generating integrated controllers. The modular large-current parallel starting and generating integrated controller comprises a starting control module, a plurality of power generation modules and a function module, and can realize large-current power generation output and large-current motor driving output; all modules are controlled in a full-digital mode, so that control is flexible, expansion is convenient, and power density is high; the starting control module is used as a main module to communicate with other modules through a serial port bus, read data and send commands, and adopts separate layout of large-current and high-voltage signals and small signals to reduce mutual interference; the starting control module serves as a main module and can communicate with other devices through RS422, CAN, RS485 and the like. An engine starting controller and a generator power generation controller can be organically integrated together, part of power devices and control logic are shared, the weight and the size are reduced, and seamless connection of starting and power generation is achieved.

Description

technical field

[0001] The present invention relates to the field of integrated start-up controllers, and more particularly, to a modularized high-current parallel start-up integrated controller and a control method. Background technique

[0002] This integrated controller is mainly used in aircraft platforms, vehicle platforms and ship platforms, and is used with brushless permanent magnet synchronous motors to start engines and supply power to airborne equipment, vehicle equipment or shipborne equipment.

[0003] In the traditional engine starting and power generation system, the engine starting is completed by an independent starter motor, and the power generation is also completed by an independent generator and power generation controller; this kind of starter motor is usually a brushed DC motor, which drives the engine power output through a deceleration mechanism When the shaft rotates, the starting time and the starting target speed are fixed, which cannot be set fle...
