Advanced dsp concepts in todays world!!!

Most of the Microprocessor –aided UPS systems continue to depend on the analog op-amp controls and they lack speed required for high frequency inverte
r control.
Therefore, harmonics are not eliminated in the output wave form, insisting on the large output LC-filter circuit.
With the availability of low cost- high performance DSP chips characterised by the execution of most instructions in one instruction cycle, complicated control algorithms can be executed with speed, making very high sampling rate possible for digitally controlled inverters. High speed DSPs are now capable of executing over 30 million instructions per second (MIPS).
