Power Electronics


Due to an editing error, the last paragraph on page 20 of “Part 1 — SPICE Simulation Provides Advantages for DSP-Based SMPS,” in the March 2009 issue of PET contains several errors. The text should have read:

“The later representation is seen to be identical to a delay line, with z-n representing a delay of nT seconds. Transfer functions, including impedance and admittance functions are described as polynomial ratios of the form G = N/D, where N = a0 + a1z-1 + … anz-n and D = 1 + b1z-1 + … + bnz-n are the numerator and denominator polynomials, respectively. Notice that b0 = 1. Then rearranging the following equation with D' = D-1:”
