HighQ Power develops advanced power electronics utilizing Wide-Bandgap (WBG) semiconductors. We engineer systems that deliver breakthrough power efficiency and density, overcoming the physical limits of traditional silicon.
Solid-State Transformer (SST)
Solid-State Transformer (SST)
Overview
A modular, scalable replacement for legacy 50/60 Hz Medium Voltage Transformers that directly converts to 800 VDC.
Radically reduces physical volume, cutting system weight from a traditional ~2000 kg/MW down to just ~50 kg/MW.
Enhanced Efficiency
Achieves 99% to 99.5% conversion efficiency, minimizing energy waste and reducing thermal management requirements.
Fault-Tolerant Redundancy
Built-in intelligence allows submodules to automatically detect faults and safely bypass themselves. The stack features enough headroom to ensure continuous, full-power operation without downtime.
Modular Scalability
Easily scales to meet diverse regional Medium Voltage (MV) grid standards, ranging from 6.6 kV up to 35 kV.
Direct 800 VDC Conversion
Designed to support next-generation power architectures by directly converting MV AC to an 800 VDC bus.
Rapid Deployment
Utilizing standardized components and SMD assembly enables manufacturing lead times of 3-6 months, compared to the backlog of several years for current 50 Hz transformers.
Hybrid Solid-State Circuit Breaker (H-SSCB)
Hybrid Solid-State Circuit Breaker (H-SSCB)
Overview
A scalable SiC-based enhancement for mechanical Circuit Breakers that reduces arcing and current chopping, significantly extending mechanical lifetime.
Mechanical breakers typically suffer from current chopping during interruption. Our Hybrid SSCB solution assists the mechanical breaker during this phase and protects the load from over-voltage.
Longer life
By assisting the circuit breaker during arcing, we reduce the wear on the mechanical contacts, and protect it from re-arcing, significantly improving the breaker's lifetime.
Retrofit
Next to a full solution, the semiconductor stack can be retrofit to existing circuit breakers, enhancing lifetime and performance
Integrated monitoring and communication
H-SSCBs can include measurement, diagnostics, event logging, and communication interfaces to support smart grid, building automation, and predictive maintenance. That makes them more like a protection module plus metering and control, instead of just an analog overcurrent device.
