The dual-circuit relay 2 connects the brake coil 5 with the electrolytic capacitor 4 Switch between parallel and series circuits. The common end of the dual-circuit relay 2 is connected to the brake coil 5, the normally closed contacts of the dual-circuit relay 2 are respectively connected to the negative and positive electrodes of the capacitor 4, and the normally open contacts of the dual-circuit relay 2 are respectively connected to the positive and negative electrodes of the capacitor 4. The power supply 1 is connected to a normally closed contact of the dual-circuit relay 2 and the positive electrode of the capacitor 4. The diode 3 is connected between the power source 1 and the dual relay 2 and the capacitor 4.

The reverse diode can give a loop to the back EMF, by doing work to consume the induced electromotive force of the relay coil, to prevent the induced potential of the relay coil from damaging the driver or other components when the power is turned on and off. The specific models of diode 3 (D1) and freewheeling diode D3 can use RSIM.
可以理解的是,双路继电器2的常闭触点与常开触点可以根据实际需求进行切换设置,并不影响电路的功能。It can be understood that the normally closed contact and the normally open contact of the dual-circuit relay 2 can be switched and set according to actual requirements, and the function of the circuit is not affected.
