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 in high frequency mode, but the high frequency mode is only suitable for large load When the load is small, the conduction loss of the switch tube increases and the efficiency is low, which not only leads to high hardware loss and high power consumption of the drive control circuit, but also is not conducive to further improving the energy efficiency of the load

Description
technical field [0001] The present invention relates to the field of drive control, in particular to an operation control method, a drive control circuit, 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 swit...
