Abstract

The invention provides a circuit control method and device as well as equipment. The method comprises the following steps: sending a first control signal to an electronic switch in a circuit by virtueof a first control unit, wherein the first control signal is used for controlling the state of the electronic switch to be on or off; and by virtue of a second control unit, sending a second controlsignal to a dynamic load of the circuit according to the state of the electronic switch, wherein the second control signal is used for controlling the dynamic load to be connected or disconnected withthe circuit. By virtue of the method provided by the invention, the problems that a leak current exists after turn-off of the electronic switch in related technologies, fake turn-off can appear at anoutput terminal and then a voltage exists at the output terminal are solved.

Description

technical field [0001] The present invention relates to the field of circuits, in particular, to a control method, device and equipment for circuits. Background technique [0002] The development of the Energy Internet is growing stronger and stronger, and the types and quantities of equipment that need to be controlled are also increasing. Traditional mechanical switches are not suitable for integration and installation due to their large size. The electronic switch can not only realize the switch function, but also save a lot of installation space. However, compared with mechanical switches, electronic switches are not physical switches. Due to the characteristics of electronic devices, commonly used electronic switches such as MOS and thyristors have junction capacitance at the switch control terminals. In the use of the energy Internet industry, when AC and DC coexist, there is a leakage current after the electronic switch is turned off, which leads to the situation th...
