Abstract: A motor drive apparatus includes: a DC-side capacitor charged with direct current power; an inverter unit comprising multiple top switches and bottom switches, performing a switching operation so as to convert power stored in the DC-side capacitor into alternating current power, and outputting the converted alternating current power to a motor; a shunt resistor for detecting a current flowing through the DC-side capacitor; and a controller for controlling the inverter unit to perform dynamic braking for stopping the motor. Before the dynamic braking is performed, the controller controls the inverter unit to gradually increase a phase current flowing through the bottom switches.

Abstract: A mobile terminal of the present invention comprises: a front case having a display unit disposed on a front surface thereof; a rear case coupled to the front case at the rear of the front case to form an inner space; a main board located in the inner space and comprising mounted components coupled to a surface thereof; a shielding sheet laminated on a back surface of the main board; and a wireless charging coil located in the inner space, wherein the shielding sheet has empty spaces at positions where the wireless charging coil and the mounted components overlap with each other. Accordingly, the main body of the mobile terminal can be prevented from becoming thick by forming the shielding sheet for enhancing the performance of the wireless charging coil in a shape that does not overlap with the wireless charging coil and the mounted components at the same time.
