Title:
FLYBACK CIRCUIT
Document Type and Number:
Japanese Patent JP2015122610
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce the mounting space required for flyback circuit.SOLUTION: A flyback circuit according to the present invention includes: a motor 160; a power supply 110 for supplying a voltage to the motor 160; a flyback line 194 connecting the motor 160 by bypassing; a second field-effect transistor element 186 provided in the flyback line 194; a snubber circuit connected in series to a positive voltage line 190 and a gate terminal 188 of the second filed-effect transistor element 186, and connected in parallel to a power-supply switch 170; and a resistor 148 connected between the gate terminal and a source terminal of the second field-effect transistor element 186.
