MOSFETs: energy use and power loss calculator?
…moving charge carriers, or in other words, requires flowing a current. The reverse recovery loss can often be the largest single loss on a MOSFET. Transistors: IGBTs vs MOSFETs? IGBTs…
Offshore wind: will costs follow Moore’s Law?
Some commentators expect the levelized costs of offshore wind to fall another two-thirds by 2050. The justification is some eolian equivalent of Moore’s Law. Our 16-page report draws five contrasts….
Moore’s law: causes and new energies conclusions?
Moore’s law entails that computing performance will double every 18-months. It was proposed in 1965. And since then, chips have consistently sustained this pace. We argue such exponential progress has…
Solar inverters: companies, products and costs?
…modules in an AC waveform that can be transmitted across power grids or used in electronic devices. This is achieved via pulse width modulation (explained here) using IGBTs and MOSFETs…

DC-DC power converters: efficiency calculations?
…the MPPT in solar, to wind turbines, to charging and discharging batteries, such as in electric vehicles. DC-DC converters invariably contain one or more MOSFETs, diodes, inductors and capacitors. Think…
Maxwell’s demon: computation is energy?
…X is the number of possible microstates of a system. Hence if you think about the smallest possible transistor in the memory of a computer, which is capable of encoding…
Solar decline rates: causes and solutions?
…inverter strategy is explored on pages 11-13. Our work supports the shift from central inverters towards smaller inverters, possibly micro-inverters at utility scale. Companies covered in the report include Enphase,…
Hillcrest: ZVS inverter breakthrough?
…below). This AC power signal can be used to feed power into the grid, or to drive the electric motors in an electric vehicle. The switches are MOSFETs or IGBTs….
