Driving method and driving device using the same

A driving device comprising:

• a multi-state driver configured to sequentially generate multi-state configurations, which include at least one low-impedance configuration, wherein when the multi-state driver generates the at least one low-impedance configuration, the multi-state driver generates a grounding voltage;
• a pulse transformer having a primary winding and a secondary winding, the primary winding is electrically connected to the multi-state driver, and the pulse transformer is configured to detect the multi-state configurations;
• a switching device electrically connected to the secondary winding;
• and
• a control device electrically connected to the switching device, when the pulse transformer detects the multi-state configurations, the pulse transformer uses the multi-state configurations to sequentially drive the switching device to electrically connect the secondary winding to the control device and charge the control device through the switching device, drive the switching device to disconnect the secondary winding from the control device, drive the switching device to electrically connect the secondary winding to the control device and discharge the control device through the switching device, and drive the switching device to maintain an electrical connection between the control device and the secondary winding to transfer the grounding voltage to the control device and maintain a voltage provided to the control device, wherein the switching device further comprises:
• a first electrical switch electrically connected to the secondary winding and the control device;
• a second electrical switch electrically connected to the secondary winding, the control device, and the first electrical switch;
• and
• a capacitor electrically connected to a control terminal of the first electrical switch, to hold first electrical switch ON when discharging the control device.
