Program simulates Class D power amps
HB-SIM helps engineers design half-bridge (Class D) power amplifiers or
power converters. The program simulates the steady-state periodic
time-domain waveforms 100 to 1,000 times faster than using Spice. HB-SIM
accounts for the ac and dc resistances of all components, plots waveforms
and harmonic spectra of currents and voltages, and displays the computed
powers in tabular form. It can sweep any parameter and plot computed
result versus the swept parameter. The program runs on IBM PCs and
compatible computers. ($495–available now.) Design Automation, Inc.
