Abstract
A system includes: a refrigerant compressor including an electric motor; a single printed circuit board (PCB); a drive that is disposed on the single PCB and that includes switches that control the application of power from a battery to the electric motor; and one or more processors disposed on the single PCB, the one or more processors configured to: determine a speed command for the refrigerant compressor based on one or more operating parameters; and actuate the switches of the drive based on the speed command.
Claims14
A system, comprising:
- a refrigerant compressor including an electric motor;
- a single printed circuit board (PCB);
- a drive that is disposed on the single PCB and that includes switches that control the application of power from a battery to the electric motor;
- one or more processors disposed on the single PCB, the one or more processors configured to:
- determine a speed command for the refrigerant compressor based on one or more operating parameters;
- and
- actuate the switches of the drive based on the speed command;
- and
- a first interface disposed on the single PCB, the first interface having a plurality of input and output pins, the first interface being one of a male type interface and a female type interface, the first interface configured to receive first power from the battery via a first one of the input pins, to receive a second power from the battery via a second one of the input pins, to be connected to a network bus, to receive the one or more operating parameters via the network bus, and to receive an output of an ignition sensor that indicates whether a vehicle is ON or OFF via a third one of the input pins.
A single printed circuit board, comprising:
- a drive that is disposed on the single PCB and that includes switches configured to control the application of power from a battery to an electric motor of a refrigerant compressor of a cooling system;
- one or more processors disposed on the single PCB, the one or more processors configured to:
- determine a speed command for the refrigerant compressor based on one or more operating parameters;
- actuate the switches of the drive based on the speed command;
- and
- an interface disposed on the single PCB, the interface having a plurality of input and output pins, the interface being one of a male type interface and a female type interface, the interface and configured to receive a first power from the battery via a first one of the input pins, to receive a second power from the battery via a second one of the input pins, to be connected to a network bus, to receive the one or more operating parameters via the network bus, to receive an output of an ignition sensor that indicates whether a vehicle is ON or OFF via a third one of the input pins.
A method, comprising:
- by one or more processors disposed on a single printed circuit board (PCB), determining a speed command for a refrigerant compressor based on one or more operating parameters;
- by the one or more processors, actuating switches of a drive based on the speed command,
- wherein the drive is disposed on the single PCB and includes the switches, wherein the switches are configured to control the application of power from a battery to an electric motor of the refrigerant compressor of a cooling system;
- by an interface disposed on the single PCB and having a plurality of input and output pins, receiving a first power from the battery via a first one of the input pins, the interface being one of a male type interface and a female type interface;
- by the interface, receiving a second power from the battery via a second one of the input pins;
- by the interface, receiving an output of an ignition sensor that indicates whether a vehicle is ON or OFF via a third one of the input pins;
- by the one or more processors, communicating via a network bus via the interface;
- and
- by the one or more processors, receiving the one or more operating parameters via the network bus and the interface.
