Q.1 Set. (C) A staircase modulation method is used to derive an AC voltage of 230V from a 48V automotive battery using a DSP controller. (a) Describe the various components required along with circuits and modes of operation. Clearly show the waveforms for one device: Controller PWM waveform, Gate waveform output from the driver, Vds (drain to source) for the same device. Explain the method used to derive the gate signals for the modulation scheme with a suitable sketch. [10] (b) (c) Q.1 Set.
