Not Available VPT Inc. proposes to develop a low cost, ultra-compact, thick-film hybrid dc-dc converter for a diode laser application. The converter will employ state-of-the-art chip and wire technology, high frequency switching, reliable magnetic feedback, in a hermetically sealed package. The converter will be triple output; with power for the diode laser, a thermo-electric cooler, and a Q-switch with a PRF frequency in the tens of kilohertz. The power supply will feature low output voltage ripple to minimum phase and amplitude noise in the intended LIDAR or LADAR application and an EMI filter designed to meet Mil Std 461. However, because it will be based on a VPT standard product design, it will also be very low cost. These standard products are designed to meet Class H military screening levels. This combination of features is unique in the industry and is made possible by an innovative multi-layer hybrid structure. In Phase I, VPT Inc. will develop detailed design requirements, build a breadboard, verify operation, perform a thick-film hybrid layout, fabricate a dummy load to simulate the characteristics of the diode laser, and test the breadboard with the simulated load. In the Phase I option, VPT will build a triple output hybrid dc-dc converter module.
