Advanced Power Electronics for Electrified Systems
Commercializing multi-source inverter technology that simplifies power conversion architecture for demanding electrified drivetrain and energy storage applications.
01 — About Us
Nexora Powers is a deep-tech venture originating from Queen's University, commercializing breakthrough research in multi-source power inverter topology. Our technology eliminates intermediate conversion stages that plague conventional systems.
We target sectors demanding high-density, high-reliability power conversion: underground mining electrification, heavy industrial drives, and hybrid energy storage platforms where system efficiency directly impacts operating economics.
02 — Technology Overview
Our patented topology accepts multiple independent DC energy sources and produces regulated AC output in a single conversion stage — eliminating the DC bus aggregation step conventional designs require.
Each DC input (battery, capacitor, fuel cell) connects directly to dedicated inverter legs. No prior aggregation needed.
Proprietary modulation scheme coordinates switching events across legs, maintaining output waveform quality with reduced switching frequency per device.
Architecture supports regenerative operation, enabling energy recovery from drivetrain back into storage — critical for mining haul cycles.
03 — Applications
04 — Key Advantages
The modified modulation scheme reduces switching events per device per cycle. Lower switching frequency per leg means proportionally reduced switching losses — a primary contributor to inverter inefficiency at high power levels.
Eliminating the DC bus combining stage removes multiple power semiconductors, gate drivers, passive filtering components, and associated thermal management infrastructure from the bill of materials.
Sources with different voltage levels and output characteristics can be directly accommodated without source-matching DC-DC converters. The modulation algorithm handles energy flow balancing between inputs algorithmically.
Reduced switching losses translate directly to lower junction temperatures in power semiconductors. Lower thermal stress extends device lifetime and reduces heatsink volume requirements — critical in space-constrained mobile platforms.
