Document Type and Number:
WIPO Patent Application WO/2011/086945
Kind Code:
A2
Abstract:
The power circuit comprises a voltage conversion part converting an input voltage entered in accordance with a voltage of a power source to generate an output voltage and outputting the generated output voltage to the motor and a current detection part outputting a first signal in accordance with a current flowing through a given part of the power circuit. The voltage conversion part lowers the voltage value of new output voltage being generated when the current detection part outputs the first signal.
