Digital current mode control for multiple input converters
… current mode control on multiple-input (MI) converters is studied. As for MI topologies having a central energy transfer inductor, the predictive constant on-time current-mode control can greatly reduce both the design and digital realization efforts needed. By doing digital constant on-time …

Design of a wide input supply range buck-boost converter
Buck-boost converters allow the flexibility of stepping-up and stepping-down the input supply to generate a regulated output, thus making them very attractive for applications with wide input supply range. Currently, off-the-shelf buck-boost converters require a minimum operating voltage of 1.8V. …

Voltage regulation of a series stacked system of digital loads by differential power processing
… DPP topology implemented with bi-directional buck-boost converters. Some of its dynamic drawbacks are pointed out and a topological modification to counter those drawbacks is proposed. We then develop a linear control to regulate processor core voltages in a series stack of 4 cores. A …

Energy efficient control for power management circuits operating from nano-watts to watts
… limited to 1.1-6.3nW. A low switching frequency boost converter is employed to increase the input voltage to a higher voltage usable by CMOS circuits in the sensor. Ultra-low power digital control circuits with timers help keep the quiescent power of the power management unit down to 544pW. …

Asynchronous differential power processing for true maximum power point tracking of photovoltaic sub-modules
This thesis examines maximum power point tracking (MPPT) at the photovoltaic (PV) sub-module level, but in the context of large arrays. Central communication carries large overheads, and neighbor-to-neighbor communication can have long propagation times in large arrays, so a communication-less …
