Motor driving control apparatus and electric apparatus

An electric apparatus, comprising:

• a motor driving control apparatus, comprising:
• an inverter configured to drive a motor;
• a separation switch configured to block a current from the inverter to a power source;
• and
• a controller configured to instruct the separation switch to separate the power source from the inverter and control the inverter to perform switching according to a speed and a braking target torque, upon detecting an event that braking should be performed without passing a regenerative current to the power source from the inverter,
• wherein the controller comprises:
• a first generator configured to generate a first signal according to the speed and the braking target torque;
• and
• a second generator configured to generate a second signal to cause the inverter to perform switching, based on the first signal generated by the first generator, and the first generator is configured to set, according to the speed and the braking target torque, a lead angle and/or an amplitude corresponding to an average duty cycle with respect to a waveform of the first signal.
