Cinergia EL+ vHF, Regenerative High Frequency AC Electronic Load

CINERGIA offers a unique Regenerative AC Electronic Load designed to work in a 360 to 900Hz frequency range, used mainly in aircraft generator’s test platforms. The use of this equipment has two main advantages. On the one hand, it allows significant energy and power savings, as morethan 90% of the energy is fed back into the grid. Being, in many occasions, the energy saving the most important point since energy requirements of the laboratory will be reduced to the losses of the motor-generator bank plus the losses of the electronic load. On the other hand, it allows better control and greatly simplifies testing. Common test procedures require the generator to be loaded with a fixed power factor (cos fi) while the generator speed (and therefore frequency) changes. This requires a continuous adaptation of the inductance value to maintain a constant cos fi throughout the frequency sweep. The use of real inductors requires the use of many inductors, which will be switched on or off to modify the inductance or the use of variable. With CINERGIA’s High-Frequency Electronic loads it is only necessary to set the desired current and delay (cos fi) and the dynamic PLL will automatically synchronise the current with the voltage keeping the power factor fixed.

CINERGIA has developed a line of regenerative Electronic Load products capable of working in a frequency range of 360 to 900Hz. It was designed to simulate the different loads that can be found in the aircraft. This family of products includes 3 models designed to provide all the necessary tools to perform tests in this field.

All products include the high-frequency feature, and in addition, are combined with other functionalities, in AC and DC.

CINERGIA’s EL+ vHF has two main advantages: it allows significant energy and power savings. And secondly, allows better control and greatly simplifies testing.

CINERGIA’s EL+ vHF/AC emulates the electrical behaviour of passive and active devices connected to the grid. In addition, its grid stage as an Active Rectifier produces clean sinusoidal currents with very low harmonic distortion, it will emulate the 50/60Hz loads in the aircraft.

CINERGIA’s EL+ vHF/DC can create a +270/0/-270V network, emulate a DC load profile or even emulate the back up battery. It also includes specific software that will allow the testing and characterisation of the batteries.
