NASA Glenn Research Center (GRC) needs a high voltage and high power, ripple generator and impedance measurement system capable of performing analysis on both DC and AC circuits to support lab testing and development. The AVL Ripple Generator & Impedance Measurement System or equal shall have the capability to inject controlled sinusoidal and triangular type currents from 30Hz to 200kHz, perform current ripple injection and perform impedance measurements via a parallel/capacitively coupled type injection, perform ac ripple injection onto DC, single-phase AC; and three-phase AC networks.
