  • Hopf oscillator based device comprising inverters
    Patent number: 11545913
    Abstract: The present disclosure relates to a device, comprising a first inverter, wherein the first inverter is configured to invert a DC input voltage into an AC output voltage, a first controller, wherein the first controller is configured to provide a reference voltage for the first inverter on the basis of an AC output current of the first inverter, a second inverter, wherein the second inverter is configured to invert a DC input voltage into an AC output voltage, a second controller, wherein the second controller is configured to provide a reference voltage for the second inverter on the basis of an AC output current of the second inverter, wherein the first inverter and the first controller form a first Hopf oscillator, wherein the second inverter and second controller form a second Hopf oscillator, and wherein the first Hopf oscillator is coupled to the second Hopf oscillator.
