Patent ID: 7999503

Claim:
A control module for an inverter in a vehicle, the control module comprising: a first circuit card assembly; a microprocessor mounted on the first circuit card assembly, the microprocessor being configured to: determine a phase modulation command for a first motor phase; and determine a modulation criterion for the inverter; and an integrated circuit mounted on the first circuit card assembly and communicatively coupled to the microprocessor, the integrated circuit being 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, wherein the control module is configured to: modulate a first switch in the inverter based on the first modulation signal; and modulate a second switch in the inverter based on the second modulation signal, wherein the first switch and the second switch comprise a phase leg of the inverter.
