Abstract:
An electric powered work machine according to one aspect of to the present disclosure includes a motor. The electric powered work machine includes a first line connecting a positive electrode of a battery to the motor. The electric powered work machine includes a second line connecting a negative electrode of the battery to the motor. The electric powered work machine includes a third line connecting the first line to the second line. The electric powered work machine includes a first capacitor disposed on the third line. The electric powered work machine includes a rectifier disposed on the third line. The rectifier limits or inhibits an electric current flowing from the second line to the first line through the third line. The electric powered work machine includes a first circuit connected to the third line. The first circuit has impedance that is other than zero, and bypasses the rectifier.
