Abstract

The invention discloses a control method and device of a hybrid switch device, equipment and a medium, and relates to the field of power electronics. The method comprises the steps of determining thatthe hybrid switch device enters a power transmission mode; in the switch conduction stage, under the condition that the first mechanical switch unit is in an off state, controlling the second mechanical switch unit and the semiconductor switch unit to be conducted in sequence; in the power transmission stage, controlling the first mechanical switch unit to be in an on state, and controlling the semiconductor switch unit to be in an off state; and in the switch off stage, under the condition that the first mechanical switch unit is in an off state, controlling the semiconductor switch unit andthe second mechanical switch unit to be off in sequence. According to the hybrid switch device control method and device, the equipment and the medium provided by the embodiment of the invention, thesafety of the switch device can be improved.

Description

Technical field [0001] The present application relates to the field of power electronics, and in particular to control methods, devices, equipment and media for hybrid switching devices. Background technique [0002] With the rapid development of the power electronics field, there are increasing demands for circuit control, especially for high-voltage and high-current circuits. [0003] At this stage, switching devices are often used to control the transmission of current in circuits. Switching devices can interrupt the current or allow the current to flow. Since switching devices often affect the safety of electricity and determine the control sensitivity of electronic devices, the safety of switching devices is also crucial. However, the safety of switching devices is often affected by instantaneous large current shock or thermal failure. Contents of the invention [0004] The control method, device, equipment and medium of the hybrid switch device provided by the embo...
