Explore our military-grade, maritime-rated, and severe-environment uninterruptible power conversion solutions optimized for 400V 3-phase grid compatibility and off-grid stability.
In complex electrical environments across Greece—ranging from coastal shipyards in Piraeus to distributed photovoltaic-wind microgrids across the Cyclades—power quality is plagued by non-linear loads, severe harmonic distortion, and reactive power losses. Conventional non-isolated 3-phase front ends rely heavily on bulky 50Hz isolation transformers, which add significant mass, introduce acoustic noise, and degrade system efficiency.
Our advanced Isolated 3-Phase Power Factor Correction (PFC) Modules incorporate active high-frequency galvanic isolation directly within the power conversion topology. By utilizing a two-stage matrix conversion architecture integrated with synchronous rectification, these modules simultaneously convert 3-phase AC power (380V–480V RMS, line-to-line) to a tightly regulated DC bus while forcing input currents to track input phase voltages in real time. This achieves an outstanding Power Factor (>0.99) and reduces current Total Harmonic Distortion (THD) below 3%, adhering strictly to EN 61000-3-2 and IEEE 519 standards.
Replacing traditional fast-recovery diodes with actively driven, ultra-low RDS(on) MOSFETs eliminates the fixed forward-voltage conduction loss inherent in conventional diode bridges. Under heavy output currents, this design reduces internal thermal dissipation by up to 45%, enabling compact sealed enclosures to operate effectively under extreme Mediterranean summer ambient temperatures (+45°C to +70°C conduction-cooled).
By providing high-pot isolation (4250V dc input-to-output and input-to-baseplate), our modules prevent common-mode noise propagation and eliminate ground loops between the incoming 3-phase utility or generator grid and sensitive downstream electronics (such as FPGA controllers, sonar arrays, and medical telemetry).
Greece presents a unique operating matrix for high-reliability power systems: aggressive marine environments, islanded microgrids, rapid expansion of green energy, and heavy naval defense infrastructure.
Port automation systems, shore-to-ship cold ironing interfaces, and heavy gantry crane rectifiers demand active harmonic correction to prevent localized grid collapse. Our ruggedized, anti-salt-corrosion IP68-rated modules supply clean regulated DC power to variable frequency drives (VFDs) while protecting harbor substations from severe reactive current penalties imposed by public utilities.
Non-interconnected island grids experience extreme frequency variations (45Hz–65Hz) and dynamic voltage swings due to solar PV fluctuation and wind intermittency. Our wide-frequency input isolated PFC front ends automatically lock onto volatile diesel-solar hybrid grids, ensuring uninterrupted output power for telecommunication towers and municipal water desalination plants.
Naval surface vessels and military installations in Salamina and Souda Bay operate under strict MIL-STD-1399 (Type I, 3-phase balanced power) and MIL-STD-461 (EMI/EMC) standards. Our Mil-COTS isolated PFC modules provide uncompromised phase-balance loading across line-to-line networks, avoiding line-neutral voltage shifts during combat system cycling.
As Greece accelerates its energy transition toward 80% renewable electricity generation by 2030 under the updated NECP framework, the industrial grid faces fundamental power quality challenges. The phase-out of traditional lignite power plants in Western Macedonia reduces total system inertia, making grid frequencies more sensitive to industrial harmonic pollution.
System integrators, electrical engineers, and factory managers across Athens, Patras, and Heraklion are mandated by IPTO (ADMIE) and HEDNO (DEDDIE) to enforce rigorous power quality compliance at the point of common coupling (PCC). Integrating our Isolated 3-Phase PFC Modules into industrial power conversion chains provides:

Industrial programs in defense, rail, and heavy energy infrastructure require component lifecycles spanning 20+ years. We guarantee product longevity support, preventing premature redesign costs and providing documented obsolescence protection for Hellenic procurement managers.
Our field application engineering (FAE) team works directly with Greek electrical design offices to perform system thermal modeling, EMI filter simulation, and stress derating evaluations prior to layout freeze—reducing prototype iteration cycles by up to 60%.
Clear engineering insights addressing grid compliance, environmental robustness, and product selection.
Non-isolated PFC topologies pass common-mode noise directly from the AC line to the DC bus and require a large, heavy 50Hz line isolation transformer to satisfy safety and ground loop requirements. Isolated 3-Phase PFC modules embed high-frequency planar transformers inside the module, reducing system weight and volume by over 70% while offering up to 4250V dc galvanic isolation. This is essential for island microgrids and maritime systems prone to line surges, neutral shifts, and floating ground faults.
All our modules feature high-efficiency synchronous rectification (up to 96.5% peak efficiency), significantly minimizing heat output. Engineered with aluminum baseplates or potted IP68 ruggedized enclosures, they operate reliably at baseplate temperatures ranging from -40°C to +100°C. Conduction cooling via cold-plate mounting or direct attachment to cabinet walls enables fanless operation in sealed, dust-tight, and salt-mist-resistant outdoor enclosures.
Yes. Our isolated 3-phase PFC modules feature wide-input frequency tracking algorithms (ranging natively from 45 Hz to 65 Hz for standard industrial lines, and up to 400/800 Hz for defense and aviation platforms). They retain active unity power factor (>0.99) and low THD (<3%) even when supplied by islanded diesel generators or microgrid inverters experiencing transient speed droop and voltage distortion.
When integrated with our recommended companion EMI filter modules, our isolated PFC front ends enable the complete power system to meet EN 61000-3-2 (Limits for harmonic current emissions), IEEE 519 standards for power quality control, and EN 55032 / MIL-STD-461 conducted emissions limits. This avoids harmonic penalty surcharges from Greek utility providers (HEDNO/ADMIE).
