Problems solved by technology

[0004] (1) The circuit structure of the Boost type PFC module is simple, that is, the charging and discharging process of the inductor is controlled by the switch tube, but the efficiency of the Boost type PFC module is low, and the switching loss is large
[0005] (2) The efficiency of the bridgeless totem pole PFC module is higher than that of the Boost type PFC module. However, the bridgeless totem pole PFC module usually works at high frequency or power frequency, which not only leads to the failure of the drive control circuit High hardware loss and high power consumption are not conducive to further improving the energy efficiency of the load

Abstract

The present invention provides a drive control method, device, home appliance and computer-readable storage medium. The drive control method includes: detecting the operating current input to the load in the power supply signal, and recording the input duration of the operating current ; according to the operating current and the input duration, control the switching device to work in a first mode or a second mode, wherein the first mode is configured as a mode for controlling the switching device to be turned off, and the second The second mode is configured as a mode in which the switching device operates according to a specified pulse driving signal, so that a given current in the second mode follows the AC voltage input to the load. Through the technical scheme of the invention, the working efficiency of driving the load is improved, and the circuit power consumption and hardware loss are reduced.

Description

technical field [0001] The present invention relates to the field of drive control, in particular, to a drive control method, a drive control device, a household electrical appliance, and a computer-readable storage medium. Background technique [0002] PFC (Power Factor Correction, power factor correction) technology is widely used in drive control circuits, and its main function is to improve the power consumption efficiency of electric equipment (load). [0003] In related technologies, PWM (Pulse-Width Modulation, pulse width modulation signal) is usually used to drive the switch tube to be turned on or off. Commonly used PFC modules include Boost-type PFC modules and bridgeless totem-pole-type PFC modules. Two types of PFC The module has at least the following technical defects when driving the load: [0004] (1) The circuit structure of the Boost-type PFC module is simple, that is, the charging and discharging process of the inductor is controlled through the switch t...
