Abstract

The invention provides an output voltage closed-loop control method and an output voltage closed-loop control system for a portable power generator. The method comprises the following steps of acquiring an electrical signal of the output voltage the portable power generator; performing amplification processing on the electrical signal, and performing analog-digital conversion on the amplified electrical signal, so as to obtain a digital signal; performing computing processing on the digital signal, so as to obtain output digital quantity; performing digital-analog conversion on the digital quantity so as to obtain an analog signal; performing amplification processing on the analog signal and then outputting the amplified analog signal. The system comprises a signal extraction module, a first amplifying circuit, an analog-digital conversion module, a processor module, a digital-analog conversion module, a second amplifying circuit and an output module which are sequentially connected. Through acquiring the electrical signal of the output voltage of the portable power generator, and performing closed-loop control sequentially including first amplification processing, analog-digital conversion processing, computing processing, digital-analog conversion processing, second amplification processing and then output on the electric signal, the output voltage stability of the portable power generator is improved.

Description

technical field [0001] The invention relates to the technical field of generator output voltage control, in particular to a closed-loop control method and control system for the output voltage of a portable generator. Background technique [0002] At present, the portable generators that are widely used usually have low power, which causes the output voltage to vary greatly with the increase or decrease of the load. However, the output voltage of the portable generator will vary greatly and cause damage to the load it carries or even scrap it, thus greatly reducing the service life of the load. Contents of the invention [0003] The purpose of the present invention is to provide a closed-loop control method and control system for the output voltage of a portable generator to solve the problem in the prior art that the output voltage of the portable generator varies greatly and the service life of the load is low. [0004] In order to achieve the above object, the first as...
