    Abstract: A heat pump apparatus includes a compressor, a motor, an expander, a generator, and a variable-speed converter. The variable-speed converter is connected to the generator and converts alternating current generated by the generator into direct current. The variable-speed converter continues to control driving of the generator after an operation stop trigger occurs for lowering the speed of the motor and stopping the operation of the heat pump apparatus at least until a value of current flowing through the generator becomes equal to or less than a predetermined value. The variable-speed converter stops the working of the generator after the value of current flowing through the generator becomes equal to or less than the predetermined value.
