With a total of six patents under his name, Schwander continues to push the boundaries of innovation in this critical area of technology.
Latest Patents
Schwander's latest patents include groundbreaking designs for DC-DC converters utilizing a DC electric power source. The first patent describes a converter that integrates an inverter and a conversion unit powered by a transformer. This design features a controlled rectifier built from saturable inductors and power diodes. Key to this invention is a series reactive circuit linked with the transformer that cooperates with the controlled rectifier to achieve phase displacement of the voltage applied at the primary of the transformer relative to the current flowing through it. The regulation of this phase displacement is managed by a control voltage, adjusting dynamically to the output voltage variations of the converter.
His second patent elaborates on a method for DC-DC conversion that also employs a DC current source. The configuration again includes an inverter and a conversion unit, characterized by controlled magnetic switching made possible through power diodes and saturable inductors. This innovation introduces a regulator that generates a control voltage corresponding to the output voltage, facilitating the regulation with the injection of said control voltage into a circuit featuring smoothing inductors. During the operational cycle, the method creatively locks one power diode while allowing the other to switch into conduction mode, thereby creating a phase displacement between the input voltage and current of the conversion unit. The angle of this phase displacement is dictated by the control voltage.
