A switch control method of a driving power generation system

Abstract

The invention discloses an on and off control method of a travelling power generation system. The travelling power generation system comprises an engine, an alternating current power generator, a direct current power generator, a power generation controller and a power increase module, wherein the power generation controller comprises a power generator control module and an inversion module; the engine is connected with the alternating current power generator and the direct current power generator respectively to drive the alternating current power generator and the direct current power generator to rotate; the power generator control module is connected with the alternating current power generator to control the alternating current power generator to operate and output electric energy; aninput end of the power increase module is connected with the direct current power generator and a storage battery respectively; an output end of the power increase module is connected in parallel with an output end of the power generator control module to form a common bus as an input of the inversion module; and the power generation controller is in communication connection with the power increase module by a CAN bus. A power takeoff generation system performs uniform control on the power generation controller and the power increase module; and the power generation controller and the power increase module are hot standby each other.

Description

technical field [0001] The invention relates to the technical field of driving power generation systems, in particular to a method for controlling on-off of the driving power generation system. Background technique [0002] The emergence and development of vehicle-mounted power generation power supplies have been around for a long time. Most of them are used in military combat vehicles to provide sufficient power for radar, computer and communication equipment. With the continuous advancement of power electronics technology and the automotive industry With the rapid development of assembly technology, some large civilian vehicles, such as emergency rescue vehicles, temporary communication auxiliary vehicles and even RVs, which are loaded with more electrical equipment, are equipped with vehicle-mounted power generation power systems. At present, when the power generation system is running, most of the silicon rectifier generators are driven by the belt. The inverter will boo...
