Abstract
"The purpose of Phase II is to fully design, test and hardware demonstrate an 80KW frequency agile converter-inverter based upon (digitally controlled) concurrent integration of polybridge inverters. Phase II will develop and demonstrate the ability todigitally control multiple concurrent polybridger inverters as to enable high switching frequency MOSFET-based high-voltage amplifiers in a small package. When combined with the proposed drive technology using DSP derived PWM control for current balancedoutput, the design could meet the extended Navy goal of enabling the power source for the wideband towed-array to be integrated directly within the towed array itself rather than ship-borne. The Phase II concurrent polybridge 80KW converter-inverter willdemonstrate low output noise and frequency agility to 10KHzBENEFITS: The proposed digital controlled "concurrent polybridge" would bring a wholly new capability into the high power market. Commercial applications include wherever inverter performance withfrequency agility is required, in a system with low noise performance similar to a linear amplifier. It provides a modular architecture where a range of units can be simultaneously paralleled to increase or decrease overall power capability. QorTek hasteamed with Universal Voltronics a major vendor of commercial and U.S. Navy power converters who have been steadily establishing commercial markets in medicine, electronics and automation ind
