Patent number: 9627954Abstract: A buck power converter creates a desired output voltage from a greater input voltage with higher efficiency than linear regulators or charge pumps. For compact-size and cost sensitive products, the use of the buck power converter is hindered mainly because of lack of physical space and increases in the cost of the passive components like the inductor and capacitor. Techniques are presented to reduce the sizes of the passive components so that they can be integrated on-chip or in-package or on board. A signal converter in the buck power converter determines the duty cycle of a switching control signal. The switching control signal would ordinarily have driven a power switching circuit that provides current to the inductor in the buck power converter. The signal converter outputs a modified (multiphase) switching control signal that includes multiple separated on-periods that taken together approximate the duty cycle of the switching control signal while maintaining the same control loop frequency.Type: GrantFiled: June 6, 2011Date of Patent: April 18, 2017Assignee: SanDisk Technologies LLCInventors: Deepak Pancholi, Bhavin Odedara

Patent number: 9621225Abstract: A method of two-way communications over a power distribution network in which outbound communication signals (O) and an inbound communication signals (I) modulate a time-varying waveform propagated through the network, on the low voltage side of the network. An outbound signal waveform is detected at a customer location (C) with remote communication equipment (RCE) at the customer location then producing a return or inbound communication signal. A corresponding inbound signal is produced in an associated voltage waveform and this signal is detected and processed by a distribution concentrator unit (DCU) at the sending end of the network. The transmission and detection of signals on the low voltage side of the network requires less energy than the generation, propagation, detection, and processing of signals on the high voltage side thereof.Type: GrantFiled: January 8, 2016Date of Patent: April 11, 2017Assignee: Aclara Technologies LLCInventors: John B. Hessling, Mario K. Deschenes, Robert W. Richardson, Scot M. Gingerich
