Embodiment Construction

[0034] The purpose of the present invention is to effectively reduce the weight of the airborne equipment of the whole machine, improve the power-to-weight ratio of the system, and further improve the accuracy of control. For this reason, a multi-functional converter based on dual DSP is proposed. The power supply control of the synchronous motor realizes the starting of the aeroengine. After the startup is completed, the device realizes the control of other actuating systems on the machine by controlling the power supply to the permanent magnet synchronous motor. The main power circuit part of the device is shared, and the control circuit part realizes precise control of the three-stage synchronous motor and the permanent magnet synchronous motor respectively, realizes multi-functional multiplexing, and improves the utilization rate of airborne equipment.

[0035] The multifunctional converter is aimed at the characteristics of the three-stage synchronous motor. The device ca...

Abstract

The invention provides a multifunctional converter based on dual-DSP. The multifunctional converter comprises a main power circuit and a control circuit. The main power circuit comprises a three-phaseuncontrollable rectifier, a power-on flexible charging loop, a filter circuit, an H-bridge inverter circuit, a three-phase full-bridge inverter circuit and a drive circuit; the control circuit comprises a CPU minimum system, an analog acquisition and conditioning circuit, a discrete magnitude input and output circuit and a position detection and decoding circuit. As for characteristics of a three-level type synchronous motor, an exciter in a starter generator and a main electricity generator can be powered to achieve the starting function of an aero-engine, and meanwhile, the device can powerthe permanent-magnet synchronous motor to achieve the electric drive function of the actuation system on the motor; partial sharing of the main power circuit is achieved, the control circuit partially adopts the dual-DSP and CPLD configured CPU minimum system, according to different instructions, different PWM pulse signals are generated to the drive circuit, and then the inverter circuits are driven to output and power different motors.

Description

technical field [0001] The invention relates to a power converter, in particular to a dual-DSP-based multifunctional converter for aviation. Background technique [0002] Aircraft weight is an important indicator, which is closely related to aircraft flight safety, performance, manufacturing cost, operating cost, etc. Effective control and weight reduction of aircraft empty weight can not only reduce R&D and manufacturing costs, but also provide Flexible loading space, and can improve the flight stability of the aircraft. At present, the high-power electric starting systems of aero-engines at home and abroad have begun to adopt the scheme of brushless starting / power generation. Usually, a starter controller is used to drive a three-stage motor in China to start an aeroengine. Power generation integration. However, the actuation systems on the aircraft for the control of flaps, ailerons, spoilers, and fuselage doors are currently equipped with additional motor controllers,...
