摘要： A motor driver includes an inverter, a multiphase pre-driver circuit, a controller and motor relays. The inverter includes pairs of an upper-arm switching element and a lower-arm switching element being connected in series between a ground line and a power supply line, and supplies power to a multiphase motor by converting direct current power of a battery. The multiphase pre-driver circuit drives the upper-arm and lower-arm switching elements. The controller commands the multiphase pre-driver circuit to drive the switching elements, and controls electrical conduction from the inverter to the multiphase motor. The motor relays interrupt a current flowing from the multiphase motor to the inverter during an off state. The multiphase pre-driver circuit includes a charge pump. The motor relays are turned on by an output voltage of the charge pump during an operation of the charge pump in a situation apart from that the controller provides an instruction.

摘要： A driving device drives a motor including a rotor having a neodymium rare earth magnet. The driving device includes an inverter, a first detector that outputs a first detection signal corresponding to a motor driving current supplied to the motor, a protection level setting unit that sets an overcurrent protection level, a second detector that outputs a second detection signal corresponding to a driving state of the motor, and a control device. The control device executes first control of lowering the motor driving current immediately after the motor driving current corresponding to the first detection signal exceeds the overcurrent protection level. When the protection level setting unit lowers the overcurrent protection level to a new current level based on the second detection signal, the control device executes second control of lowering the motor driving current to a level lower than the new current level.

摘要： A driving device is used with a compressor including a motor including coils. The driving device drives the motor. The driving device includes an inverter connected to the coils, a connection switching unit to switch a connection state of the coils between a first connection state and a second connection state, a controller to control the inverter and the connection switching unit, and a compressor state detection unit to detect a state of the compressor. When the connection state of the coils is the first connection state, the controller controls the motor based on a first detection value detected by the compressor state detection unit and a first threshold. When the connection state of the coils is the second connection state, the controller controls the motor based on a second detection value detected by the compressor state detection unit and a second threshold.
