RECENT ADVANCES IN PHOTOVOLTAIC SOLAR CELLS INDICATE A VAST NEW MARKET MAY SOON BE EMERGING. THIS PROPOSAL COVERS THE ELECTRICAL INTERFACE OF SUCH A SYSTEM, THE PHOTOVOLTAIC INVERTER REQUIRED TO CONVERT THE SOLAR ARRAY'S DC ENERGY TO UTILITY-COMPATIBLE AC. A 10 KW, DUAL RESONANT INVERTER IS PROPOSED HAVING SEVERAL ADVANTAGEOUS PROPERTIES OVER PREVIOUS APPROACHES. THE INVERTER WILL BE DESIGNED TO OPERATE NEAR RESONANCE TO VIRTUALLY ELIMINATE SWITCHING LOSSES, MINIMIZE EMI, AND DRASTICALLY REDUCE REVERSE BIAS SECOND BREAKDOWN OF THE INVERTER'S POWER TRANSISTORS. THE TWO INVERTER OUTPUTS, PHASED TOGETHER USING A NOVEL MODULATION PROCESS, WILL SYNTHESIZE A LOW DISTORTION OF 60 HZ CURRENT THAT WILL FEED INTO THE UTILITY POWER GRID. DC CONVERTERS.
