Abstract: An output control apparatus of a motor includes a controller formed by having a power device to bridge a motor and a power supply. The controller incorporating the power device provides voltage control modulation during different motor speeds so as to fix the recharging voltage at the DC bus in a specific range without involvement of any voltage converter. It is unnecessary to use additional complex circuits or other DC/DC converters to reduce the voltage recharged from the motor running at a high speed. In addition, space for the apparatus is reduced, and the specification and function of the original controller can be maintained without trading off work in redesigning the motor system.
