Title:
MOTOR DRIVING CIRCUIT AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/037013
Kind Code:
A1
Abstract:
Embodiments of the present application provide a motor driving circuit and a terminal device, which can reduce the cost. The motor driving circuit comprises: a power supply module, configured to output an alternating current voltage; an inductive coupling module, comprising a primary side inductor and a secondary side inductor and configured to couple the alternating current voltage to a linear motor; at least one parallel-connected capacitor bank, each parallel-connected capacitor bank comprising at least one switch module and at least one parallel-connected capacitor, a first electrode of the parallel-connected capacitor being respectively electrically connected to one end of the secondary side inductor and a positive end of the linear motor, a second electrode of the parallel-connected capacitor being electrically connected to a first end of the switch module, and a second end of the switch module being respectively electrically connected to the other end of the secondary side inductor and a negative end of the linear motor; and a control module, electrically connected to a control end of the switch module, and configured to control on or off of the switch module. When at least one switch module is controlled to be switched on, the parallel-connected capacitor electrically connected to the switched-on switch module is connected in parallel to the secondary side inductor, so as to increase the alternating current voltage coupled to the linear motor.
