Abstract:
1. An inverter for use in a vehicle having a DC energy supply, the inverter comprising: a primary stage within the housing configured to boost a first DC output of the DC energy supply to a second DC output, wherein the primary stage controls switching operations of a number of switching devices used to facilitate boosting the first DC output to the second DC output according to measurement of the first DC output and independent of a feedback measurement of the second DC output; a secondary stage within the housing configured to invert the second DC output to an AC output, wherein the secondary stage controls switching operations of a number of switching devices used to facilitate inverting the second DC output into the AC output according to measurement of the second DC output and independent of measurement of the AC output; wherein the primary stage includes a primary controller within the housing configured to control switching operations of the primary stage based on measurement of the first DC output; wherein the secondary stage includes a secondary controller within the housing configured to control switching operations of the secondary stage based on measurement of the second DC output; and wherein the secondary controller is unable to communicate measurement of the second DC output to the primary controller.
