Abstract: An electrical power converter comprises a first direct current line connected to a first direct current source, a second direct current line connected to a second direct current source, an alternating current line connected to an alternating current motor, a controller, and a pulse generator. The controller determines a required torque of the alternating current motor. The controller also determines a voltage command value that substantially minimizes a copper loss of the alternating current motor while providing the required torque of the alternating current motor. The pulse generator generates an output voltage according to the voltage command value at the alternating current output.

Abstract: An electronically commutated motor (ECM 20) has terminals (56, 62) for connection to a DC power source (63). It has a permanent-magnet rotor (22), also a first and a second series circuit (40, 50) in each of which a stator winding strand (30, 32) is connected in series with a controllable semiconductor switch (34, 44), which two series circuits are connected in parallel to form a parallel circuit (52). In addition to the strand-connected switches (34, 44) typically found in an ECM, in a supply lead to said parallel circuit (52), a third controllable semiconductor switch (60) controls energy supply from the DC power source (63). In order to increase motor efficiency and minimize the size of any motor capacitor required, special switching steps are performed so that electromagnetic energy, remaining in the winding(s) after shutoff of power application, is converted into motor torque, instead of being dissipated as heat.

Abstract: In an electrical system, such as an orthogonal, midplane architecture, backdrilling vias may enable selective connectivity to components of the midplane board without custom connectors and/or contacts. A first contact and a second contact may be received within a shared backdrilled via at opposite ends. The backdrilled via may establish electrical connectivity between the first contact and an internal conductive path of a midplane board. Because the backdrilling removes a portion of the via, the first contact and the second contact may be electrically isolated. The electrically conductive path between the first mounting contact and the internal conductive layer may be used for low-speed communications channel, power, ground, control signaling, or the like.
