Patent ID: 8085565

Claim:
An inverter for use in a vehicle having a DC power supply, the inverter comprising: a primary stage having switching devices operable in response to primary stage control signals to boost a first DC output of the DC power supply to a second DC output; a secondary stage having switching devices operable in response to secondary stage control signals to invert the second DC output into an AC output; a primary stage controller configured to output the primary stage control signals used to control the switching devices of the primary stage to boost the first DC output to the second DC output; a secondary stage controller configured to output a frequency modulated signals representative of the secondary stage control signals needed to control the switching devices of the secondary stage to invert the second DC output into the AC output; a signal converter configured to convert the frequency modulated signals into the secondary stage controls signals used to control the switching devices of the secondary stage to invert the second DC output into the AC output; and a regulator configured to power both of the primary and secondary stages using the first DC output of the DC power supply.
