How do Magna-Power Electric Vehicle Test Power Supplies handle 800V and 1200V powertrain requirements?
Magna-Power supplies offer models natively rated up to 1000V DC and 1500V DC, making them ideal for testing 800V nominal EV battery packs, traction inverters, and high-voltage DC fast chargers. Units can be connected in master/slave parallel or series configurations under a single unified controller, providing full voltage and current scaling without degrading regulation accuracy or system response time.
Why is low stored output energy critical when choosing a power supply for SiC double-pulse testing?
Silicon Carbide (SiC) and Gallium Nitride (GaN) power switches operate at extremely high $dv/dt$ rates. During double-pulse testing, any severe resonance or accidental short circuit will discharge the power supply’s output capacitance directly into the power module under test. Magna-Power’s current-fed architecture utilizes significantly smaller output capacitor banks than traditional voltage-fed supplies, vastly reducing stored energy and preventing catastrophic destruction of prototype SiC devices.
What hardware options prevent reverse-EMF damage during motor drive dynamic braking?
During vehicle deceleration or dyno motor braking, the electric traction motor operates as a generator, dumping back-EMF back onto the DC high-voltage bus. Magna-Power provides Option BD (Internal Blocking Diode), which prevents reverse current from reaching internal power stages. Additionally, pairing MagnaDC power supplies with MagnaLOAD electronic loads creates a fully integrated bidirectional testing rig capable of sinking regenerative energy safely.
How do water-cooled EV test supplies compare to air-cooled models in continuous high-power test bays?
For high-power testing above 150 kW (such as full drivetrain dynamometers or megawatt charging stations), air-cooled supplies transfer substantial thermal heat into the test room, requiring expensive facility HVAC infrastructure. Magna-Power ML Series water-cooled power supplies transfer up to 95% of dissipated heat directly into a facility’s closed-loop chilled water system, operating silently while maintaining a compact, fully sealed enclosure protected from industrial dust and contaminants.
Can Magna-Power supplies execute automated drive cycle profiles (WLTP, FTP-75, ISO 21498)?
Yes. Magna-Power instruments come standard with Ethernet/LXI, USB, RS-232, and isolated analog user I/O, with optional Modbus TCP and IEEE-488 GPIB interfaces. Through SCPI commands, Python libraries, or NI LabVIEW drivers, engineers can program high-speed voltage and current profiles to simulate exact real-world driving cycles, battery dropouts, and ISO 21498 fault conditions automatically.
What lead times can global buyers expect for made-to-order EV test systems?
Thanks to complete vertical integration at our Flemington, New Jersey factory—where sheet metal fabrication, transformer winding, PCB assembly, and final burn-in are executed under one roof—typical lead times for made-to-order Magna-Power supplies are just 4 to 6 weeks. Select fast-moving configurations are also available immediately from ready-to-ship inventory.
How does linear MOSFET technology in MagnaLOAD electronic loads benefit fuel cell and battery testing?
Standard switch-mode electronic loads generate high-frequency pulse-width modulation (PWM) switching noise, which interferes with delicate micro-volt battery sensors and distorts Electrochemical Impedance Spectroscopy (EIS) measurements. MagnaLOAD ALx Series loads utilize a linear MOSFET topology operating in non-switching linear mode, delivering zero switching noise and providing clean, high-fidelity DC sinking for battery cell and fuel cell research.
