Abstract: Power is provided from a power source and a status of the power source is signaled by controlling a waveform of an AC voltage generated from the power source. The status may include, for example, a capacity of the power source. In some embodiments, a frequency of the AC voltage may be controlled to signal the status. The power source may include, for example, an uninterruptible power supply (UPS), and signaling a status of the power source may include controlling an inverter of the UPS to signal the status. Related systems are also described.

Abstract: An integrated circuit is provided with an MCU, which is configured to generate a PWM control signal that is free of switching pattern information therein. A current-estimating gate driver is provided, which is responsive to the PWM signal. This gate driver is configured to drive first and second gate terminals of first and second parallel switching devices (within a hybrid switch) with gate signals that establish a second switching pattern within the hybrid switch. These gate driving operations are performed in response to measuring a first voltage associated with a terminal of the hybrid switch when being driven by gate signals that establish a first switching pattern within the hybrid switch that is different from the second switching pattern. The duty cycles of the gate signals associated with the second switching pattern are unequal and the duty cycles of the gate signals associated with the first switching pattern are unequal.

Abstract: An apparatus includes a plurality of semiconductor switches. A first bus interconnects first terminals of the semiconductor switches in a first chain and provides a first impedance between the first terminals of switches of the first chain. A second bus interconnects second terminals of the semiconductor switches in a second chain and provides a second impedance greater that the first impedance between the second terminals of the switches of the second chain. The apparatus may be implemented as a laminated bus assembly including respective overlapping conductor plates, wherein the second bus includes a plate having subregions defined by features, such as slots or grooves, that provide the second impedance.
