Classification: CPC G  H | IPC G  H

Claim 13:
14. A system, comprising:
a controller, comprising:
a driver communicatively coupled to one or more transmitters, wherein the driver is configured to transmit a continuous control signal via the one or more transmitters to one or more respective power modules; and
first processing circuitry configured to:
receive one or more inputs indicative of a shutdown of the one or more respective power modules;
in response to receiving the one or more inputs:
transmitting a first command to driver control circuitry communicatively coupled to the driver, wherein the first command is configured to disable the driver; and
transmitting a second command to transmitter control circuitry communicatively coupled to the transmitter, wherein the second command is configured to prevent power from being provided to the one or more transmitters; and

a power module of the one or more respective power modules, wherein the power module is configured to control an operation of a power converter to provide power to a motor, wherein the power module is communicatively coupled to a first transmitter of the one or more transmitters, and wherein the power module comprises:
driver circuitry configured to control the operation of the power converter; and
second processing circuitry, at the power module, configured to:
receive the continuous control signal from the first transmitter;
detect a lack of communication from the driver based on the continuous control signal;
in response to detecting the lack of communication:
transmit a third command to gating signal enable circuitry at the power module to disable the driver circuitry; and
transmit a fourth command to driver power circuitry to prevent power from being provided to the driver circuitry.
