Abstract: A deadtime optimization apparatus and method may determine when it is safe to turn a switch ON, eliminating the need to have a switch controller purposely insert a deadtime period in the algorithm (i.e., it can go back to producing ideal PWM). Since the decision of when it is safe to turn ON the switch may be achieved through measurement, it is expected that the length of time may change for each pulse as the operating conditions change. Therefore, the apparatus and methods of the present invention may take on a dynamic characteristic because the safe to turn ON (STTO) time may vary for each pulse.

Abstract: A packaged power supply device (10) is configured to output multiple supply voltages, which are converted from a single input voltage (VIN). The packaged power supply device may can be configured as a DC/DC converter, which is operable to output each of the output supply voltages in a sequential manner, in accordance's with power up sequencing requirements of a processor-based system. The sequential output supply voltages may include: a fixed core supply voltage, a programmable core supply voltage, an input/output (I/O) supply voltage, and a logic supply voltage. These output supply voltages might be converted from an input voltage VIN, which has a wide continuous operational range (e.g., 14-50 VDC).

Abstract: When multiple motors (40) share a common DC power supply (10) via a bus (20), a system and method is provided for managing the effect of regenerative energy caused by a motor. The regenerative energy may be sensed, e.g., by a power electronics controller (50, 50?). In response, one or more of the other motors currently in operation may be controlled to operate according to a reduced power factor. Thus, the excess energy is consumed without adding any new components or increasing the amount of work performed in the system.
