Abstract

One or more embodiments of the invention disclose an input power form identification method and device and electronic equipment. The method comprises steps that to-be-identified input power is received through a power rectification unit, the input power is processed, and the processed input power is transmitted to a detection rectification unit; the detection rectification unit processes the input power through a resistive load to obtain a waveform; the sampling voltage-dividing network carries out voltage reduction processing on the waveform so as to obtain a voltage range which can be used by the single-chip microcomputer; the single-chip microcomputer carries out analog-to-digital sampling conversion on the waveform after voltage reduction processing, and identifies the form of input power based on a near zero point identification method and a mean value nearby periodic pulse identification method. The method is advantaged in that the input power can be identified, and identification accuracy is high.

Description

technical field [0001] This document relates to the field of electronic technology, in particular to an input electrical form identification method, device and electronic equipment. Background technique [0002] In the field of power converter technology, the power converter needs to realize the transformation of the form of electric energy to match the power demand of the load. [0003] Traditional power converters can be divided into four types: DC-DC, AC-DC, DC-AC, and AC-AC. It can be seen that the input form does not take into account both DC and AC forms, and the same AC input power generally cannot Both three-phase AC and single-phase AC are available. With the development of new energy technology, the form of electric energy utilization is innovative. For example, the application of power converters such as new energy special vehicles is faced with the adaptability of various input sources, including DC input power, three-phase AC input power, and single-phase AC in...
