Abstract

The invention discloses a standby control circuit, a standby control method and an electrical apparatus. The standby control circuit comprises discharging resistors, a discharging control chip, a filter and an X-capacitor, wherein the discharging control chip and the discharging resistors are in series connection so as to form a discharging circuit; the discharging control chip is used for controlling the connection of the discharging circuit when an input AC power supply is powered off; the X-capacitor is used for filtering differential mode interference; and the X-capacitor is in parallel connection with the discharging circuit and the filter. By employing the technical scheme mentioned above, the discharging control chip can control the working state of the discharging resistors, so that the standby power consumption is saved, efficient and energy-saving effects are achieved, and the standby control circuit is simple in structure and low in cost.

Description

technical field [0001] The invention relates to the field of standby control, in particular to a standby control circuit, a standby control method and electrical equipment. Background technique [0002] The load of the frequency converter in the prior art in the standby mode mainly includes the main control device and its peripheral circuits, the drive circuit, and the filter circuit; in the standby mode, all three circuits have current flowing through them, and consume power during the production process. [0003] For the filter circuit, according to the requirements of "Safety of Household and Similar Electrical Appliances", if the residual voltage of the plug meets the standard requirements, and the X capacitor in the filter circuit exceeds 0.1uF, no discharge resistor is needed; if it cannot be satisfied, a discharge resistor must be added. until the residual pressure requirement is met. [0004] If the X capacitor exceeds 0.1uF, increase the discharge resistance, and i...
