Unique Series Amplifier Integration

Unlike conventional ripple test setups, BOLAB's revolutionary design places the amplifier directly in series with the HV power supply, ensuring:

Superior Test Accuracy: Eliminates signal distortion, providing accurate ripple injection across all frequencies.
Increased Efficiency: Minimizes power loss and maximizes test energy delivered to the Device Under Test (DUT).
Enhanced Safety: Advanced coupling methods safeguard both personnel and equipment by effectively isolating and controlling high-voltage signals.

High Speed

Even Load Dump pulses are covered with BOLAB´s, unique in the world, high-end test systems for Electric Vehicles.

3000 V/ms for 20 V is required in VW80300 with a 7µs rising time.

BOLAB´s solution: better than 1µs!

250 V/ms increase for 150 V:

HV supply		High Frequency 4 Quadernt Supply		Combination in series

High Voltage DC Power Supply + 4 Quadrant Amplifier In Series

Setup

As coupling network transformers (CDN) are limited in speed, frequency ranges, amplitude and especially allow only sine interferences, this solution cannot be used for Load Dump applications. Load Dump requirements are both part of LV 123 and VW 80300 standards.

Our most flexible solution is the combination of a high voltage power supply in series to our 4 quadrant amplifiers. Individual transients and even Load Dump requirements are possible.

In addition, BOLAB’s modular design allows the adaption to almost all manufacturers of high voltage power supplies. There is no need to purchase an additional power supply if one is already available.

Advantages

Highly flexible
Transient interferences
Load Dump possible
Start from DC
High-frequency testing without losses

Disadvantages

More safety needs to be implimented
