What are Regatron AC Power Supplies? They are high-performance, modular power electronics designed for professional grid simulation, renewable energy testing, and electric vehicle (EV) infrastructure validation. These systems offer full 4-quadrant operation, which means they can both source and sink AC power with extreme precision. Consequently, they are the industry standard for Australian engineers who need to simulate real-world grid disturbances or test bidirectional inverters. By providing a stable and programmable AC source, Regatron units ensure that your equipment complies with rigorous international and local safety standards.
Why Efficiency Matters in High-Power Testing
In the modern laboratory, energy efficiency is no longer just a “nice to have” feature. When testing high-power systems, the heat generated by traditional linear power supplies can be immense. Regatron AC Power Supplies utilise advanced switching technology to achieve efficiencies of up to 94% or higher. Therefore, you spend less on electricity and require smaller cooling systems within your facility.
Furthermore, Regatron systems are designed with regenerative capabilities. This means that when the unit is in “sink” mode—for example, when testing a solar inverter feeding back into the grid—the energy is returned to the local facility mains. As a result, the total cost of ownership is significantly reduced over the lifespan of the equipment. In a high-cost energy market like Australia, this regenerative feature provides a massive competitive advantage for R&D labs and production lines.
The Versatility of 4-Quadrant Technology
A primary reason engineers choose Regatron AC Power Supplies is their 4-quadrant capability. But what does this actually mean for your testing procedures? In simple terms, a 4-quadrant source can operate as both a programmable AC source and a programmable AC load. It can handle any combination of voltage and current polarity, making it essential for testing “active” components that push power back into the system.
Common applications for this technology include:
-
Solar Inverter Testing: Simulating a stable grid to see how an inverter reacts to voltage dips or frequency shifts.
-
V2G (Vehicle-to-Grid): Testing EV chargers that allow the vehicle battery to support the home or grid.
-
Microgrid Simulation: Creating a “virtual grid” to test how various renewable sources interact without risking damage to the actual utility infrastructure.
-
UPS Validation: Stress-testing uninterruptible power supplies under complex reactive loads.

Where Regatron Systems Are Used in Australia
The Australian energy landscape is changing rapidly. With the world’s highest uptake of rooftop solar, our grid faces unique stability challenges. Consequently, Regatron AC Power Supplies have become vital tools for local manufacturers and utility providers. They are used to ensure that new technologies can survive the “dirty” power conditions often found at the end of long rural feeders.
Renewable Energy Integration
Australian standards like AS/NZS 4777.2 dictate how inverters must behave when grid conditions fluctuate. Regatron’s TC.ACS series allows engineers to automate these tests. They can precisely simulate “Volt-Var” and “Volt-Watt” responses, ensuring the inverter remains compliant with Australian Clean Energy Council requirements.
Electric Vehicle Infrastructure
As the EV transition accelerates, the demand for fast-charging stations grows. These stations must be tested against harmonics and voltage fluctuations. Regatron AC Power Supplies provide the clean, programmable power needed to simulate these conditions. Because the systems are modular, they can be scaled up to test even the highest-capacity ultra-fast chargers.
Procedures for Setting Up a Grid Simulation
When using Regatron AC Power Supplies for grid simulation, following a structured procedure is essential for safety and data accuracy. While the software interface is intuitive, the physical power involved requires careful management.
-
System Configuration: Define the phases (Single-phase, Three-phase, or Split-phase) within the ACS Control software.
-
Limit Setting: Before energising the output, set strict current and voltage limits to protect your Device Under Test (DUT).
-
Waveform Generation: Use the integrated function generator to create the required waveform. You can select standard sine waves or import complex, non-linear harmonics.
-
Disturbance Injection: Program specific events, such as a 50ms voltage sag or a frequency ramp, to observe the DUT’s protective response.
-
Monitoring: Use the real-time data logging to capture the voltage and current waveforms at the point of common coupling.
Disclaimer for Procedures: The procedures described above are provided as general examples of grid simulation workflows. Always refer to your specific site safety protocols, the equipment’s official operating manual, and relevant Australian Electrical Standards before performing high-voltage testing.
Common Mistakes in AC Power Testing
Even with high-end Regatron AC Power Supplies, certain mistakes can lead to inaccurate results or equipment damage. One frequent error is neglecting the “Reactive Power” limits. Some engineers focus solely on the Real Power (kW) and overlook the Apparent Power (kVA). If your load is highly inductive or capacitive, you may hit the current limit of the supply sooner than expected.
Another common pitfall is using inadequate cabling for high-frequency testing. Regatron units can operate up to 1000 Hz or higher. However, at these frequencies, the impedance of standard cables can cause significant voltage drops and signal distortion. Therefore, always use low-inductance cables and keep runs as short as possible.
Finally, many users forget to account for the “Grid Impedance” simulation. A real-world grid is not a perfect voltage source; it has internal resistance and inductance. If you don’t program these parameters into your Regatron supply, your DUT might behave differently in the lab than it does in the field.
