Plug control device, electronic equipment and plug control method thereof

Abstract

The invention discloses a plug-pull control device, electronic equipment and a plug-pull control method of the electronic equipment. The device comprises a plug assembly. The plug assembly is used fordetecting whether the current voltage is within a set range of a zero crossing point in the plugging process with the socket; If the current voltage is within the set range of the zero crossing point, controlling the current state of the device to be controlled to change; Or, if the current voltage is not in the set range of the zero crossing point, controlling the to-be-controlled device to keepthe current state, and controlling the current state of the to-be-controlled device to change until the current voltage returns to the set range of the zero crossing point again. According to the scheme provided by the invention, the problem that the power electronic device is easily damaged when the on-off operations such as hot plug, startup and shutdown of the power electronic device such as an IGBT and a power diode occur near the peak value of the voltage can be solved, and the effect that the power electronic device is not easily damaged is achieved.

Description

technical field [0001] The invention belongs to the technical field of power electronics, and in particular relates to a plug-in control device, an electronic device and a plug-in control method thereof, in particular to an intelligent plug-in device with a soft switch function, an electronic device and a plug-in control method thereof. Background technique [0002] With the rapid development of power electronics technology, large household appliances are using a large number of power electronic devices such as IGBTs and power diodes. It is easy to generate a large inrush current, which will cause a certain degree of damage to power electronic devices such as IGBTs and power diodes, but when the breaking occurs near the zero crossing point, there is almost no damage to the power devices. Contents of the invention [0003] The purpose of the present invention is to provide a plug control device, electronic equipment and plug control method for the above defects, so as to so...
