  • Power-MOSFETs: leading companies?

    Power-MOSFETs: leading companies?

    Power MOSFETs are an energy transition technology, the building block behind inverters, DC-DC converters, EV drive trains, EV chargers and other renewables-battery interfaces. Hence this data-file is a screen of companies making power MOSFETs, especially new and higher-efficiency devices using Silicon Carbide as the semi-conductor.

  • DC-DC power converters: efficiency calculations?

    DC-DC power converters: efficiency calculations?

    DC-DC power converters are used to alter the voltage in DC circuits, such as in wind turbines, solar MPPT, batteries and digital/computing devices. This data-file is a breakdown of DC-DC power converters’ electrical efficiency, which will typically be around 95%. Losses are higher at low loads. We think there will be upside for increasingly high-quality…

  • Boltzmann energy overview?

    Boltzmann energy overview?

    The Boltzmann constant, denoted as kB, or 1.381 x 10^-23 J/K, is the most important number in thermodynamics. It denotes the rate at which a single particle will gain thermal energy (in Joules) as its absolute temperature rises (in Kelvin). It underpins the Boltzmann distribution and the Maxwell-Boltzmann distributions, which matter in modelling gases, energy…

  • Global polysilicon production capacity?

    Global polysilicon production capacity?

    Polysilicon is a highly pure, crystalline silicon material, used predominantly for photovoltaic solar, and also for ‘chips’ in the electronics industry. Global polysilicon capacity is estimated to reach 3MTpa in 2024, and global polysilicon production surpasses 1.7MTpa in 2024. China now dominates the industry, approaching 94% of all global capacity.
