Abstract

A deadbeat controlled pulse-width-modulated (PWM) inverter was designed and implemented with a VLSI microcontroller (68HC11) operating at a 2-MHz clock frequency. The system is built around a full bridge switch configuration implemented by MOSFET transistors and associated opto-coupler drivers. The system operates at a PWM pulse rate of about 2 kHz (2 106/210 ≅ 1953 Hz) and can produce standard waveforms (sine, square, triangular) as well as any arbitrarily-shaped user-defined waveform, with a maximum bandwidth of 400 Hz. The controller design was optimized by running computer simulation with the MATLAB numerical calculation software package. The experimental results for various operating conditions, including switched loads, were found to be in good agreement with the simulation analysis.
