Abstract: A modified power converter circuit utilizes an RLC circuit tuned to the frequency of any instability in the power converter circuit in order to remove the instability in the circuit output. In one embodiment, a pair of RLC circuits are connected in parallel across the input capacitor and output capacitor of the power circuit topology, respectively. The capacitor and inductor of each RLC circuit act as filters having a period with the same value as the instability created by interaction of the respective input or output capacitor with the isolation transformer inductance and expose the resistor within each the RLC circuit to only the frequency of instability.
Abstract: An electrical transformer is provided having a toroidal core; a plurality of wraps of a low impedance transmission line the low impedance transmission line including a transmission pair of first and second conductors such that the transformer creates a magnetic flux confined to interfaces between said first and second conductors and does not extend to the toroidal core, and the transformer having a coupling coefficient K arbitrarily close to 1 and a value of leakage inductance Ll arbitrarily close to 0.
