Abstract

The invention provides a hybrid switch circuit with a main path connected with solid-state switches in series, a change-over switch, a change-over system and a control method thereof. The hybrid switch circuit comprises a mechanical switch branch, a main solid-state switch branch and an energy absorption branch, wherein the main solid-state switch branch comprises one or more solid-state switchesconnected in series; the mechanical switch branch comprises a mechanical switch and a solid-state switch; the solid-state switch comprises a forward circuit and a reverse circuit which share a controllable switch circuit and an antiparallel diode. The hybrid switch circuit with the main path connected with the solid-state switch in series, the change-over switch, the change-over system and the control method thereof provided by the invention have the characteristics of being convenient to control and capable of being quickly changed over, and is compact in structure and reliable in performance.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a hybrid switch circuit and a switch device in which a main path is connected in series with a solid-state switch. Background technique [0002] At present, mechanical switching devices are generally used to control the on-off of electric power. With the widespread use of switchgear in various industries, the requirements for switches are now getting higher and higher. [0003] The diode is a common electronic component that is also used in switches. The most common function of a diode is to only allow current to flow in a single direction, that is, from the anode (also known as the positive pole) to the cathode (also known as the negative pole), and to block the current in the reverse direction. Due to this characteristic of diodes, they are widely used in electronic circuits. Diodes are now used in a variety of circuits, such as clipping circuits and switching circ...
