Abstract
Inverter-filter non-linearity blanking time and zero current clamping compensation is accomplished by comparing the average output current with the discontinuous current mode threshold values to determine when the average output current is entering a discontinuous current mode and introducing a compensation voltage to the inverter drive voltage in response to the average output current entering a discontinuous current mode to compensate for discontinuous current mode distortion of the inverter output voltage.
