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

SiC (silicon carbide) rectifiers are high‑performance power conversion systems that convert high‑power AC into controlled DC voltage and current for electrolyser systems and green hydrogen production.

Our SiC‑based rectifiers deliver high efficiency, outperforming IGBT and thyristor (SCR) technologies. This reduces operating costs and enables higher hydrogen output per kWh.

In addition, very low total harmonic distortion (THDi) eliminates the need for external compensation equipment such as STATCOMs or harmonic filters. Combined with a compact footprint and standard transformer requirements, this results in lower CAPEX and reduced installation complexity.

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)
