Abstract

The invention discloses a non-polarity electronic switch, which comprises a shell, wherein the shell is provided with pins 3 and 4 of a power supply loop and pins 1 and 2 of a driving circuit, two MOSFETs (Metal-Oxide-Semiconductor Field Effect Transistors) which are mutually connected are arranged in the shell, the gate electrodes of the two MOSFETs are mutually connected, and are then connected with the pin 1 of the driving circuit, the source electrodes of the two MOSFETs are mutually connected, and are then connected with the pin 2 of the driving circuit, and the drain electrodes of the two MOSFETs are connected with the pins 3 and 4 of the power supply loop. According to the invention, the drain electrodes are respectively connected with the pins 3 and 4 of the power supply loop, the pins 3 and 4 of the power supply loop are respectively used as the positive electrode connection end or a negative electrode connection end of the power supply loop, distinguishing the positive electrode and the negative electrode is not needed when the non-polarity electronic switch is connected, random butting can be performed without being limited by the polarity, and the installation and connection are simple and convenient.

Description

technical field [0001] The invention relates to the fields of electronic control, power conversion and power management, in particular to a non-polar electronic switch. Background technique [0002] There is no need to consider the positive and negative connection relationship when connecting the non-polar power supply, that is, the external power supply, and any positive and negative wiring can be done. At present, the conduction mode of the non-polar power supply is mainly realized by the relay, but the relay is large in size and low in reliability, and cannot meet the occasions with high reliability requirements or high switching frequency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a non-polar electronic switch, which can realize the purpose of bidirectional conducting and blocking of the power circuit. [0004] Technical scheme of the present invention is: [0005] A non-polar electronic switch, compr...
