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!

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
