Abstract :
DSP based design approach for sinewave inverters are discussed in the past [N. Kularatna, et al., 1998; N. Kularatna, 2000; N. Kularatna, et al., 1999; N. Kularatna, et al., 2000; N. Kularatna, et al., 2001]. However, due to generalized hardware in DSP chips, implementation of a control block of a sinewave inverter for precise RMS control and total harmonic distortion (THD) minimization may not be hardware efficient. As an alternative, special look-up table based FPGA approach for THD control is discussed in the paper, where no higher order harmonics are calculated individually.
