Thank you so much for your response, with respect to the Space vector modulation index "m" pulse should be given to the IGBT driver. for ex. 10ms in state s1 and next 10ms in and so on s2, s3, s4, s5, s6. By switching this way it will produce sine wave as output with the variable amplitude and frequency. In the voltage source inverter we have 6 states as mentioned above and two null states.

An FPGA can easily generate such waveforms to the gate drivers.
However, that does not clarify your requirements; what current and voltage do you want to measure? For example, do you want to measure the instantaneous current and voltage during the time each of the IGBTs is active, or just the voltage and current delivered to the load?
The speed at which you want your monitored voltages and currents determines your ADC sampling rate requirement.
The resolution of the ADC is determined by the ratio of the largest to smallest value you want to measure for any particular current or voltage, eg., if you want a range of 1V to 1mV, you need an ADC with 10-bits of dynamic range.
