Insulated-Gate Bipolar Transistor (IGBT) technology provides High Efficiency, significant reduction in Harmonic Distortion (THDi) and can improve the Power Factor to near unity without the use of auxiliary components.
Yonder ofers IGBT-based converters across Active Front End, Active Front End with DC-DC Chopper and DC-DC technology. For kW-scale projects, we also offer SiC-based bidirectional convertors
Yonder Active Front-End (AFE) converter is designed to convert AC to DC using IGBT technology which employs higher frequency switching. AFE topology reduces harmonic distortion and allows bidirectional power exchange between AC and DC allowing regenerated power to be fed back to the supply (if needed). With already
integrated filters, the module will provide smooth DC Voltage to the electrolyser with near unity Power Factor which will ensure minimum electricity consumption.

Ador offers a two-stage converter system employing a combination of Active Front End (AFE) and Phase Shift Modulation (PSM) technology. The AFE module converts the AC to constant DC voltage and with PSM technology, the constant DC voltage is converted to desired lower DC voltage.
In AFE stage the harmonics is significantly reduced while maintaining near unity power factor without additional harmonic filters and power correction circuitry. In DC-DC stage, the interleaved PSM technology provides a significant reduction in the output ripple.

Ador DC-DC Converter is designed to convert constant DC to variable DC using high frequency IGBT switching. Phase Shift Modulation (PSM) topology is used to operate the DC-DC converter, which offers reduction in the size of output filters.
This system is operated as connections of buck converters operated in parallel. This technology is ideal for direct solar to electrolyser connections. With already integrated filters, the module will provide DC Voltage with minimum ripple which will ensure the smooth operation of hydrogen electrolysers.
The silicon carbide (SiC) based semiconductor devices give better performance in terms of higher temperature operation and can be switched using higher frequency, which reduces the overall size of unit.
In SiC technology, Yonder offers:
o AC-DC: AC-DC converter is a two-stage converter system. In AC-DC module, In first stage AFE is used, giving lower harmonics and almost unity power factor. In second stage LLC based DC-DC converter is used to provide low ripple DC output as per customer requirement.
Yonder offers AC-DC and DC-DC SiC modules of 30 kW ratings which can be stacked-up and can be scalable up to multiple kW and even MW as per project requirement
