A motor control system operable to control a motor includes a motor control circuit and an inverter circuit connected to the motor control circuit and configured to connect to the motor at phase output terminals. The inverter circuit, in response to one or more output control signals indicating a deceleration instruction from the motor control circuit, implements a multi-state deceleration sequence for at least one commutation state of a commutation scheme of the motor.

Fast deceleration of PMSM and BLDC motors using recirculation braking

A wireless charging device is disclosed. The wireless charging device includes a transmitter detection coil configured to receive a first alternating current (AC) voltage signal having a characteristic associated with a receiver device. Also, the wireless charging device includes a control unit coupled to the transmitter detection coil and configured to detect the receiver device based on the characteristic of the first AC voltage signal. Further, the wireless charging device includes a driver unit coupled to the control unit and configured to convert a direct current (DC) voltage signal of an input power to a second AC voltage signal if the receiver device is detected. In addition, the wireless charging device includes a power transmission coil configured to wirelessly transmit the second AC voltage signal to the receiver device.
