Industrial & Research Applications of 800V DC Systems
The transformation toward clean grid-ties, photovoltaic arrays, and high-voltage 800V electric vehicle architectures requires a reliable 800V DC power supply as a continuous testing source. Explore direct application analyses below.
Electric Vehicle (EV) Powertrain & Battery Testing
Modern EVs (e.g., Porsche Taycan, Hyundai Ioniq 5/6, Audi e-tron) leverage 800V class battery systems to enable ultra-fast charging. Testing motor controllers, Battery Management Systems (BMS), and onboard chargers (OBC) requires stable continuous 800V DC excitation.
By utilizing the eTommens eTM-8005 or eTM-8006 in a rack setup, testing teams can emulate different battery pack states-of-charge (SoC), internal resistance, and active transient loading, verifying high-voltage component safety.
High power density, quick transient recovery (<1.5ms), programmable voltage ramps to test high-voltage relays.

Solar Photovoltaic Inverter MPPT Testing
Commercial PV string inverters operate close to open-circuit voltages of up to 1000V. Research and production test beds need to supply controlled currents modeling dynamic solar conditions (sunrise, cloud cover, shadow drop).
The programmable list-and-curve software on eTommens eTM 800V systems acts as an I-V Curve Solar Array Simulator. By setting multiple operating coordinates, engineers test maximum power point tracking efficiency with realistic input.
Programmable list mode, high voltage stability, high power efficiency (>90%).
Electrode Deposition & Semiconductor Material Stress
High-voltage electrostatic coating, ceramic breakdown verification, and crystal growing labs need extremely precise voltage increments without high starting surges or spikes.
The eTommens eTM-8001 has a 16-bit DAC converter offering a precise resolution of 12mV. This high resolution, coupled with safety interlocking mechanisms, protects researchers and test samples.
Ultra-low ripple (<50mVrms), high-precision remote sense, interlock loop.
Industrial Robotic Motor & Servo Drive Aging
Servo and AC variable frequency drives operating on high-voltage DC buses need hundreds of hours of dynamic loading to prove reliability, requiring robust continuous power under high EMI feedback.
eTommens eTM-8003 devices operate comfortably on high-voltage production test lines 24/7. Standard galvanic isolation prevents feedback electrical EMI from tampering with PLC or analog instrumentation data lines.
Galvanic isolation up to 3000VAC, 24/7 peak output endurance, RS485 Modbus remote control.
Technical Standards & Regulatory Citations
Industrial applications in photovoltaic grid-ties and electric vehicle charging verification require rigorous safety compliance. Design parameters and performance benchmarks for high-voltage DC conversion are documented by the IEEE Power Electronics Society Standards, which dictate ripple attenuation and electrical isolation limits.
