Ferroelectric Photogalvanic Generator (FEPG)

To address the Army need in pulsed power generators for advanced munitions Luminit, LLC proposes to develop a new Ferroelectric Photogalvanic Generator (FEPG). This proposed FEPG is based on the Photogalvanic (giant photovoltaic) effect. The innovation in physical principle of high-voltage generation (using photogalvanic effect) will enable the FEPG to produce high-voltage pulses without destruction of ferroelectric material. As a result, this device offers generation of high-voltage (~500 kV) pulses with regulated current. FEPG will allow producing high voltage pulses without self-destruction and in photogalvanic mode can be repetitively used, with option of the single-shot use (mode with self-destruction). In addition, photoinduced contribution from pyroelectric and piezoelectric effects will add diversity and flexibility to have multifunctional mode of operation. This is consistent with the topic requirements and directly addresses the Army PEO Missiles and Space Program requirements. In Phase I Luminit will demonstrate the feasibility of new approach by developing physical model of FEPG and providing experimental test. In Phase II Luminit, LLC plans to finalize the design of the FEPG and demonstrate that it can deliver 500 kV to various high power microwave sources. Luminit will address any manufacturing issues that would impact the production of these power supplies.
