SWITCH CIRUIT, SWITCH DRIVING APPARATUS, MOTOR SYSMEM AND MOTOR DRIVING METHOD USING THE SAME

摘要

The present invention relates to a switch circuit, a switch driving device, a motor system and a motor driving method using the same. According to an embodiment of the present invention, the switch driving device drives a power generator including a first coil and a second coil. The switch driving device includes: the switch circuit including multiple switches individually connected to the first coil and the second coil; and a control unit controlling the switches to provide the maintained energy to the second coil after the energy accumulated in the first coil is maintained for a predetermined time.
