A fully digitally controlled SPWM inverter with IGBTs as the main power devices is introduced.
Controller architecture optimization method for digitally controlled DC-DC converters
Zero drift and noise in control of digitally controlled welding positioner of arc-welding robot
To improve the VCO's tuning stability, they radically altered the circuit and created the digitally controlled oscillator, or DCO.
The thresholds inside the AGC blocks can be digitally controlled by means of on-chip 4-bit D/A converters.
