In this paper, a high efficiency, low profile design of distributed transformers (DT) for grid-tied photovoltaic (PV) inverter is presented. The proposed DTs fully integrated into the dual-flyback converter maximize the DC/DC stage efficiency in whole load conditions. The developed DTs with the built-in current sensing transformer allows the converter works in boundary conduction mode (BCM) or discontinues...
In this paper, we report a concept of integrating a monolithic buck converter power IC with in-package bondwire inductors. The power IC was designed and fabricated with a standard 0.5μm CMOS process. Multi-turn bondwires with and without ferrite epoxy glob cores are used as the filter inductor in the buck converter. A 2.5V/120mA prototype system in package (SiP) buck converter is built to operate...
This panel discusses power optimization at the system level. What are the needs and opportunities? What are examples of successful practices? Can system-level power optimizations ever be automated? Can power optimizations be the enabling event for a methodology change in system-level design?
