  • Patent number: 10797593
    Abstract: The Kappa converter circuit, as introduced herein, can be configured for step-down (buck), step-up (boost), or buck-boost operation. The Kappa converter circuit exhibits lower electromagnetic interference (EMI) relative to other buck, boost, or buck-boost topologies, such as without additional input or output filter circuits. The Kappa converter circuit can have high power handling capability and less DCR loss, for example due to a distribution of current signals through respective inductors. The Kappa converter circuit includes isolating inductors at its input and ground reference nodes to help reduce signal bounce or signal pulsations at supply and ground reference busses, thereby further reducing EMI noise due to switching in the circuit. When the Kappa converter is configured for step-up operation, the converter exhibits no right-half-plane (RHP) zero.
