摘要： A quad-T transformer in some embodiments includes a first split winding, a second split winding, and two orthogonal closed-loop windings coupled between the first split winding and the second split winding. Wires can be wound around magnetic cores. A first of the two orthogonal closed-loop windings is coupled to a first portion of each of the first split winding and the second split winding. A second of the two orthogonal closed-loop windings is coupled to a second portion of each of the first split winding and the second split winding. A bi-directional single-phase/three-phase converter includes the quad-T transformer and a Scott-T transformer with an output connected to a three-phase connection. The Scott-T transformer also has a 90-degree input connected to the quad-T transformer and a zero-degree input connected to a single-phase connection.

摘要： An augmented power converter may include a motor drive circuit. The motor drive circuit may include a motor drive transformer to convert a two-phase DC voltage to a three-phase output voltage for operating an electrical device. The motor drive circuit may also include a power control component for each phase of the two-phase voltage.

摘要： Systems and methods are provided for a dual function inrush limiting circuit (ILC). The systems and methods may include a level shift circuit (LSC). The LSC may include a Zener diode, a block diode and a capacitor. The Zener diode being in anti-series with respect to the block diode. The ILC may further include a switch electrically coupled to the LSC, an input terminal and an output terminal. The LSC may be configured to activate the switch such to electrically couple the input terminal to the output terminal. The ILC may include a direct current (DC)-DC converter electrically coupled to the output terminal. The DC-DC converter being electrically coupled to the input terminal when the switch is activated.

摘要： A system includes analysis circuitry. The analysis circuitry is configured to determine a first electrical resistance between a first terminal of a potentiometer and a second terminal of the potentiometer. The analysis circuitry is additionally configured to determine a second electrical resistance between the first terminal and a wiper terminal of the potentiometer. The analysis circuitry is additionally configured to determine a third electrical resistance between the second terminal and the wiper terminal. The analysis circuitry is additionally configured to determine a wiper resistance of the potentiometer based on the first electrical resistance, the second electrical resistance, and the third electrical resistance. The system additionally includes an output interface coupled to the analysis circuitry and configured to generate an output indicative of the wiper resistance.
