New Whitepaper released: HUBERT Power Amplifiers and the Load Dump

During the testing of electrical and electronic high-voltage components in motor vehicles, the robustness to the dynamics of the vehicle electrical system during a load dump is tested. Changes to the test voltage of up to 3000 V/ms are required. Due to their rather slow signal processing, classic DC power supplies are generally unable to achieve these slew rates.

A task for the fast HUBERT 4-quadrant power amplifiers.

New Whitepaper released: HUBERT Power Amplifier and Driving Pulsed Currents

ISO 11452-8 is a widely used automotive standard for immunity testing against magnetic fields. Recently, however, magnetic field tests with pulsed waveforms up to e.g. 500 Hz and 30 A p have been required. This task can be solved conveniently and reliably with a HUBERT A1110-40-QE-100V power amplifier in current amplifier mode.

New Whitepaper released: HUBERT Power Amplifier and Voltage Ripple

Tests in the automotive sector for the operational safety of electrical and electronic components are carried out according to various standards and factory norms, such as LV124, VDA 320, LV123 or VW80300. A sinusoidal alternating voltage is superimposed on the supply voltage of the vehicle electrical system to ensure immunity to interference from voltage ripple.
