Abstract
A switch control module including a master switch, a clamping element and a diode is provided. The master switch is configured to receive a control signal having a conducting interval and a non-conducting interval. The diode couples the clamping element and the master switch.
Claims17
A switch control module configured to control a slave switch, wherein the switch control module comprises:
- a master switch configured to receive a control signal having a conducting interval and a non-conducting interval;
- a clamping element;
- and
- a diode coupling the clamping element with the master switch;
- wherein the control signal is a periodic signal comprising a plurality of cycles, each cycle comprises the conducting interval and the non-conducting interval, the master switch is turned on when the conducting interval of each cycle of the control signal is inputted to the master switch, and the master switch is turned off when the non-conducting interval of each cycle of the control signal is inputted to the master switch;
- the slave switch comprises a switch which is turned on when the control signal is inputted to the master switch;
- wherein a positive electrode of the clamping element is connected with the slave switch, and a positive electrode of the diode is connected with the master switch;
- wherein the slave switch further comprises an inductor;
- when a magnetic force generated from an energy stored in the inductor is greater than an elastic force for disconnecting the switch, the switch is conducted;
- when the magnetic force is less than the elastic force for disconnecting the switch, the switch is disconnected to cut out the input of a power source.

A switch control module configured to control a slave switch, wherein the switch control module comprises:
- receiving a control signal or a breaking signal by a master switch, wherein the master switch and the slave switch are operated based on the control signal or the breaking signal;
- coupling with the master switch by a diode;
- and
- coupling with the diode by a clamping element;
- wherein the master switch and the slave switch are turned on in a first operating mode, the master switch is turned off and the slave switch is turned on in a second operating mode, and the master switch and the slave switch are turned off in a third operating mode.
