  • Hillcrest: ZVS inverter breakthrough?

    Hillcrest: ZVS inverter breakthrough?

    Hillcrest Energy Technologies is developing an ultra-efficient SiC inverter, which has 30-70% lower switching losses, up to 15% lower system cost, weight, size, and thus interesting applications in electric vehicles. How does it work and can we de-risk the technology?

  • Solar inverters: companies, products and costs?

    Solar inverters: companies, products and costs?

    This data-file tracks some of the leading solar inverter companies and inverter costs, efficiency and power electronic properties. As China now supplies 85% of all global inverters, at 30-50% lower $/W pricing than Western companies, a key question explored in the data-file is around price versus quality.

  • Grid-forming inverters: islands in the sun?

    Grid-forming inverters: islands in the sun?

    The grid-forming inverter market may soon inflect from $1bn to $15-20bn pa, to underpin most grid-scale batteries, and 20-40% of incremental solar and wind. This 11-page report finds that grid-forming inverters cost c$100/kW more than grid-following inverters, which is inflationary, but integrate more renewables, raise resiliency and efficiency?

  • MOSFETs: energy use and power loss calculator?

    MOSFETs: energy use and power loss calculator?

    MOSFETs are fast-acting digital switches, used to transform electricity, across new energies and digital devices. MOSFET power losses are built up from first principles in this data-file, averaging 2% per MOSFET, with a range of 1-10% depending on voltage, switching, on resistance, operating temperature and reverse recovery charge.

  • Electric vehicle cost breakdown by component?

    Electric vehicle cost breakdown by component?

    This data-file disaggregates the $30k total cost of a typical new ICE and the c$45k total cost of a typical new EV, as a sum-of-the-parts, across 25 cost lines. Drivetrain costs are similar at $8-9k each. The key challenge for the EV is the battery. The electric vehicle cost breakdown shows promise for improving power…
