Focus areas

Where Polyax delivers outsized performance and reliability.

High‑Insulation Transformers

Compact, safe isolation at medium voltage.

We design and validate high‑frequency transformers for medium‑voltage applications with a focus on insulation coordination, partial‑discharge control, and manufacturability. Our work targets compact, cost‑effective MV isolation using planar approaches where appropriate, robust winding structures, advanced materials, and thorough test plans—bridging simulation, HIL, and lab characterization. Target domains include renewables, EV, marine, aerospace, and data‑center power.

Planar Magnetics

Simulation, prototype, and characterization for high performance and reliability.

We develop planar transformers and inductors tuned for wide‑bandgap switching frequencies and high power density, emphasizing low loss, tight coupling, and consistent manufacturing. We combine 2D/3D EM modeling, thermal models, and test infrastructure to correlate predictions with hardware. Our roadmap includes scalable MV planar solutions and cost‑optimized stacks for production.

Cooling Architecture

Two‑phase and advanced air/liquid paths co‑designed with magnetics and mechanics.

We co‑design thermal pathways with power stage and magnetics, exploring two‑phase cooling and advanced air/liquid loops. We aim to translate data‑center cooling techniques into medium‑voltage power electronics, pairing CFD and sensor feedback with control algorithms (pumps/fans/valves) to improve reliability and energy efficiency at scale.

Modular Power‑Dense Converters

Repeatable sub‑modules for various applications.

We architect repeatable MV converter sub‑modules that scale across applications. Efforts include topology selection, SiC switch utilization, EMI/EMC strategies, and robust mechanical/thermal integration. We consider serviceability, instrumentation, and production test strategies early to accelerate qualification and manufacturing ramp.

Advanced Distributed Control

Multi‑node, fault‑tolerant control with synchronized sensing.

We implement novel control algorithms—current control, DC control, controllable dynamic load with programmable profiles (including data‑center load emulation), and grid‑islanding modes—across distributed nodes with time‑aligned sensing. Roadmap items include AI‑assisted control and industrial IoT for predictive diagnostics and adaptive grid interaction.

Reduced THD & Circulating Currents

Topology and control strategies to minimize distortion and parasitics across operating envelopes.

We reduce harmonics and parasitics using modulation, interleaving, and balancing strategies that hold across real operating envelopes. Our approach integrates device physics, magnetics layout, and control to suppress circulating currents, improve power quality, and meet compliance targets with margin.

Smart Protection Techniques

Fast detection and coordinated response to abnormal conditions without false trips.

We design protection that reacts in microseconds while minimizing false trips: sensing chains, MV gate‑driver protection, optical isolation, and coordinated fault response across nodes. We validate protection timing against WBG device di/dt and dv/dt realities and integrate diagnostics into system control and HIL benches.
