…energy. If this energy is going to be harnessed for useful work, then there may also be small additional losses for important power electronics, transformers and power transmission. What determines…
…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 and efficient power electronics as…
…shares of the total. We summarize how this will actually happen, and ‘how it works’, with examples, on pages 7-8. Who benefits? Electrification requires expanding power grids and power electronics….
…note that our classification of power grids excludes (a) investments in primary energy production, such as renewables, nuclear, and hydro (b) investments in large conventional power-generating plants (c) downstream investments…
…power generators have ‘inertia’. If the grid suddenly becomes short of power, due to a large new load switching on, or a large power source disconnecting, then all of these…
…16). The best opportunities to de-bottleneck short-term solar volatility include diversified and resilient power grids, gas and nuclear back-ups, super-capacitors, inter-connectors, smart-energy, demand shifting and power electronics. The merits, drawbacks…
This 14-page note explains the crucial power-electronics in an electric vehicle fast-charging station, running at 150-350kW, to charge up an entire EV in 10-30 minutes. Most important are power-MOSFETs, comprising…
…Western companies, suggesting challenged margins and strong competition. Decent inverters on the market in 2024 convert 98% of the incoming DC electricity into AC electricity, and have advanced power electronics….
…does this mean, and why does it matter? Inverters convert DC power to AC power via pulse width modulation, which is covered in our primer into electricity. Specifically, electrical switches…
…Peak power draw can be reduced over 80% with ultracapacitors. This matters as ‘peak power use’ can explain 50% of industrial power bills. At grid scale, progress is slowly accelerating….
