Abstract: A method for providing non-resonant zero-voltage switching in a switching power converter. The switching power converter converts power from input power to output power during multiple periodic switching cycles. The switching power converter includes a main switch and an auxiliary capacitor adapted for connecting to the main switch, and an inductor connectable to the auxiliary capacitor. When the main switch is on, a previously charged (or previously discharged) auxiliary capacitor is connected to the main switch with auxiliary switches. The main switch is switched off with zero voltage while discharging non-resonantly (charging) the auxiliary capacitor by providing a current path to the inductor. The auxiliary capacitor is disconnected from the main switch. The voltage of the auxiliary capacitor is charged and discharged alternatively during subsequent switching cycles.

Abstract: A device, system, and method is disclosed for improving safety of a power system. For example, a differential current may be detected using at least one sensor by temporarily enabling sampling of current flowing through one or more conductors. Additionally, current flow may be temporarily altered in order to sample current in a system. The measurements may be handled locally and/or remotely and appropriate actions may be taken to enhance the overall safety of the system.

Abstract: A circuit board adapted for use in an switching converter for connecting a plurality of switches including a first switch, a second switch, a third switch and a fourth switch. The circuit board has a layout for connecting the switches. The layout is adapted for locating the switches substantially at or symmetrically with respect to the endpoints of a right-angle cross. The right-angle cross is formed from two line segments intersecting with a ninety degree angle. The circuit board may offsets the switches perpendicularly to the line segments at the endpoints of the line segments either in a clockwise or a counterclockwise direction.
