Hydrogen rectifier and inverter/converter solutions

  • Data wave 2.png

    Lowest THDi

    THDi < 1% results in gridstability without the need for additional statcoms or filters

  • Grid support through PFC with settable PF.png

    Power factor > 0.99

    Lower line losses, less reactive power compensation needed

  • Scalable 2.png

    Small footprint

    Low commissioning and transport costs

  • Scalable up to 24 MW.png

    Scalable up to 24 MW

    Less switchgear and transformers needed

  • Endurance Testing.png

    High efficiency

    Because of the SiC (silicon carbide) MOSFET transistors higher switching frequencies can be used resulting in lower power losses

At Prodrive Technologies, we develop and manufacture SiC-based rectifiers and inverters/converters for green hydrogen production. 

SiC (silicon carbide) rectifiers are optimal power supply units (PSUs) that convert high AC power into high DC voltage and current for electrolyzers and green hydrogen production.

Our SiC‑based Hydra rectifiers deliver high efficiency, outperforming IGBT and thyristor (SCR) technologies. This results in lower OPEX and higher hydrogen output per kWh.

In addition, the low total harmonic distortion (THDi) eliminates the need for external compensation such as STATCOM or filter installations. Combined with the smallest footprint and standard transformer requirements, this leads to lower CAPEX and installation costs.

FAQ

  • Why are Statcom and filter installations not needed ?

    Because the high switching frequency of the SiC technology the THDi (total Harmonic Distortion) is extremely low (<1%)

  • Why are installation cost lower than with other technologies (Thyristor, IGBT)?

    Because of the smaller footprint, transport costs and civil costs are lower and additonal to that there are no civil cost for statcom/filter needed because these do not need to be used

  • What is the reason for the wide voltage range 0-1500VDC

    Electrolyzer inrush currents can be kept low because the ramp from 0V upwards can be adjusted, and voltages can be adapted during the lifetime of the Electrolyzer, setting the BOL (beginning of life) and EOL (end of life) voltages whenever needed. No special tranformer with tap changers needed

  • Why does SiC technology have a higher efficiency compared to Thyristor/ IGBT techology?

    SiC MOSFET (Silicon Carbide Metal Oxide Field Effect Transistor) have lower switching losses (lower Rdson / lower tail gate current)
