Latest Patents

One of Luis Zubieta's notable patents is the Transformerless Two-Phase Inverter. This invention is a DC to two-phase AC inverter that incorporates three one-leg switch mode inverter circuits or a three-phase bridge circuit along with a controller/driver circuit. The controller/driver circuit features a triangular waveform generator and two sinusoidal reference waveform generators that are out of phase with each other. The sinusoidal waveforms are generated at the desired AC output frequency, while the triangular waveform is produced at a higher frequency. This innovative design allows for efficient operation by driving one leg of the bridge circuit with a 50% duty cycle at the triangular waveform frequency, while the other two legs are driven with pulse width modulated signals. The pulse widths of each signal vary according to the discrete sinusoidal waveforms, providing each phase of two-phase AC through the inverter.
