With a total of 3 patents to his name, D'Angelo's work has advanced the efficiency and effectiveness of power supply systems.

Latest Patents

One of D'Angelo's latest patents is a method and device for pulse width modulation control. This invention employs a fully digital PWM controller utilizing a sine-triangle modulating technique. The method includes linearizing the dependence of the selected scanning frequency of the memory containing digital samples of the modulating sinusoid. This innovation improves regulation at low speeds by enhancing the resolution of selectable frequency values. The PWM driving signals produced by this digital controller demonstrate an F.F.T. that is extremely close to that of comparable PWM driving signals generated through conventional analog techniques.

Another significant patent is a fuzzy control process for switching power supplies. This process involves measuring the current on an inductor, the input voltage of the switching power supply, and the error generated between a reference voltage and the output voltage. D'Angelo's method defines fuzzy membership functions for these measurements and applies multiple fuzzy inference rules to calculate the corresponding weight functions. The results are defuzzified to obtain a real value of the duty cycle suitable for driving the switching device.
