600V Variable DC Power Supply

Inverter Testing & Renewable Energy Systems

Technical Overview

The 600V variable DC power supply is the standard for heavy industrial traction and renewable energy conversion. In 480V AC industrial environments, the rectified DC bus voltage sits around 680V, but 600V remains the nominal rating for many traction motors and inverters. This power supply enables engineers to simulate the DC Link of Variable Frequency Drives (VFDs) without a live AC mains connection. For solar energy applications, 600V is a standard string voltage for residential inverters. Testing Maximum Power Point Tracking (MPPT) algorithms requires a power supply with high output impedance modes. These units are built to withstand significant regenerative energy, often featuring integrated bleed resistors to absorb energy from braking motors.

Application Engineering Note

The industry standard for 3-phase motor drive development. 600V supplies offer the energy density required to spin large industrial motors on the dynamometer and validate the conversion efficiency of solar inverters.

Compliance Standards

IEEE 1547 (Interconnection of Distributed Resources), UL 1741 (Inverters/Converters), IEC 61400 (Wind Turbines)

Primary Use Cases

Solar Inverter MPPT Algorithm Validation

Frequently Asked Questions (600V)

How does this supply assist with MPPT testing?

Some advanced models in this 600V range feature 'Solar Array Simulation' (SAS) modes, where the I-V curve can be programmed to mimic a solar panel's output behavior under varying irradiance, allowing for static MPPT validation.

Is 600V sufficient for all VFD testing?

It is sufficient for VFDs rated for 200V-400V AC inputs (which have DC links below 600V). For 480V or 600V AC drives, you would typically need a higher voltage supply (800V+) to fully simulate the DC bus.
