Four-quadrant battery simulators offer positive and take negative current from the DUT in addition to bipolar voltage. Any capacitance in the DUT will be discharged by this, which functions more like the car’s actual battery. This battery simulator is intended to take the place of the test vehicle’s battery.
Depending on the specific application, these sources must meet a variety of requirements for power rating, voltage, slew rate, impedance, etc. In numerous cases, bi-polar current sources are given.
The Global Four-Quadrant Battery Simulator market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The VDS 200Q Series, a four-quadrant, bi-polar voltage drop simulator from EM Test, is introduced. The amplifier has the ability to “source and sink current utilising a specified voltage in both positive and negative polarities.
To replicate a wide range of occurrences occurring on a car wiring harness, the amplifier produces dips and drops, brief pauses, and voltage changes. The amplifier has a high bandwidth of 150 kHz and a low impedance of less than 10 m. It supports inrush current, low voltage drops, and quick recovery in addition to having a QuickStart feature.
Operating voltage range for the VDS 200Q Series is -15 to +60 V. It is excellent for avionics, automotive, and military industries as well as testing applications due to its high power and capacity to accommodate different battery simulation waveforms.
According to EM Test, this amplifier is used for automotive testing by Audi, BMW, ISO, Mercedes-Benz, SAE, VW, and more.The VDS 200Q series is used to model the different battery supply waveforms advised by international standards and by the needs of automobile manufacturers.
Given the wide range of requirements, the VDS 200Q series plays a significant role in meeting the manufacturer requirements in particular. Second, during tests using automotive transients, the VDS 200Q series acts as a strong DC voltage source for the DUT.All three supply voltage categories are covered by the VDS 200Q series (48 V, 24 V and 12 V). Depending on the model and application, their current capacity can reach 100 A or more.
