Abstract: A direct current-direct current (DC-DC) converter includes a plurality of switches configured to be coupled to a voltage source. The DC-DC converter also includes a transformer having a primary winding coupled to the plurality of switches and a secondary winding. The DC-DC converter further includes a first capacitor; and a second capacitor, wherein the first capacitor is coupled in series with the primary winding, the second capacitor is coupled in parallel with the secondary winding. The first capacitor, the second capacitor, and a leakage inductance of the transformer form a dual-capacitor resonant circuit.

Abstract: Light-emitting diode (LED) driver systems that are scalable and can be used for N-color LED systems are provided. An LED system having N LED strings of different color can be efficiently driven with independently controllable constant current sources for each string from a single power source. The driver system can include a power converter having an inductor.

Abstract: Advantageous machines, such as flux-switching machines (FSMs) are provided. An FSM can be yokeless and can have two rotors, which can be displaced from one another (e.g., by half a pole pitch). An FSM can be a flux-switching permanent magnet machine (FSPMM), and all magnets can be magnetized in the same circumferential direction. FSMs of the subject invention are cost-effective, have high torque density, and can operate well even under fault conditions.
