800V Variable DC Power Supply

EV High Voltage Architecture & SiC Development

Technical Overview

The shift to 800V architectures marks a paradigm shift in electric vehicle efficiency. The 800V variable DC power supply is the primary enabling tool for this transition, designed to test wide-bandgap Silicon Carbide (SiC) inverters which operate at higher switching frequencies and voltages. It enables validation of efficiency gains in the drivetrain that 400V systems cannot achieve. Beyond the drivetrain, this voltage class is mandatory for validating DC Fast Charging (HPC) stations. An 800V programmable supply can emulate a high-voltage battery pack, sinking current from the charger to verify communication protocols (CCS/NACS) and thermal management under 350kW+ loads. Safety features include interlock loops and arc detection.

Application Engineering Note

Future-proof your lab for the EV revolution. As OEMs standardize on 800V for performance vehicles, this power supply capability is the only way to validate SiC-based power electronics and high-speed charging infrastructure.

Frequently Asked Questions (800V)

Can this supply both source and sink current (Bi-directional)?

Many high-end 800V supplies designed for EV testing are indeed bi-directional. This allows them to simulate a battery absorbing energy from regenerative braking or a fast charger, and then recycle that energy back to the grid to save costs.

Why do I need 800V for EVs when most are 400V?

While legacy EVs are 400V, the industry (Porsche, Hyundai, Kia, Audi) is moving to 800V architectures to enable faster charging and thinner cabling. An 800V supply is a future-proof investment that covers both legacy 400V and next-gen 800V platforms.
