Abstract
Systems and apparatus are provided for a control module for operating an inverter in a vehicle. A control module comprises a first circuit card assembly and a microprocessor mounted on the first circuit card assembly. The microprocessor is configured to determine a phase modulation command for a first motor phase and determine a modulation criterion for the inverter. An integrated circuit is communicatively coupled to the microprocessor. The integrated circuit is configured to generate a first modulation signal based on the phase modulation command and the modulation criterion and generate a second modulation signal based on the phase modulation command and the modulation criterion.
