Cortex AC series

Description

ActionPower’s Cortex AC models are used for power testing and testing related to the local power grid. The grid simulators are full 4-quadrant AC sources with full grid feedback, designed for general electrical power testing, such as for household appliances and industrial electronics that require a programmable input source.

Waveforms

Cortex AC models can easily simulate power line disturbances (PLD) using List, Wave, Step, Pulse, and Advanced modes. Cortex AC models support 100 groups of user-defined waveforms. The synthesis function enables periodic harmonic voltage waveforms up to the 100th order based on a fundamental frequency of 40 to 70 Hz. The interharmonic function allows frequency sweeps in the range of 0.01 to 5000 Hz in addition to the 50/60 Hz fundamental frequency. This special function helps users locate resonance points.
The harmonic measurement function can measure harmonics up to the 50th order of voltage or current and display values such as fundamental voltage, DC component, and total harmonic distortion.

Waveform library

The Cortex AC models can be applied to the international standards for AC voltage testing 1741SA, IEEE1547, IEC62116, NB/T32004, T/CPSS1007-2020.
30 DST waveforms are integrated and can be called up with a single button for harmonic testing according to related standards.

Internal resistance simulation

Cortex AC models are equipped with R and L impedance simulation functions, so that the output voltage and output current are linked to R and L parameters. For example, cable impedances are simulated according to IEC61000-3-2 and 3-3 standards.

Regenerative linear AC load

In addition to the power supply function, Cortex AC models can also perform linear load simulation and feed back into the grid, enabling versatile use.
The Cortex AC series has up to 12 integrated RLC network models with flexible parameters for simulating linear load characteristics and for complete validation of product performance tests under various impedance, three-phase symmetrical, and asymmetrical load modes.
For products that require off-grid testing, such as BOBC, UPS, ESS, etc., the RLC load function of the Cortex AC series can be used to implement the conversion of a device’s source to load function. This greatly simplifies the ATE hardware configuration while enabling V2G, V2L, V2H, and other tests to be performed.

Regenerative non-linear AC load

The AC load function includes constant current, constant power, and constant impedance operating modes. Additional settings include the crest factor (CF) and power factor (PF). Rectifier mode can simulate the characteristics of a rectified load current. To do this, the CF is set from 1.414 to 5, resulting in a non-sinusoidal load function.
Integrated standard waveforms are accessed using a button for the AC load test of the corresponding standards. These include 2-pulse wave, 6-pulse wave, 12-pulse wave, 18-pulse wave, 24-pulse wave, positive half-wave, negative half-wave, leading half-wave, and trailing half-wave.

Power Hardware-in-the-Loop

The Cortex AC models have an extremely high dynamic response with a small signal bandwidth of 10 kHz, a large signal bandwidth of 2 kHz, and a response time of 70 µs. They can amplify the signals from the simulation system, signal source, or control card and output them to the object under test, implementing the PHIL function.
