<p>The DC energy is provided by A string which output 1is connected to B well known boost terminal 1and A string terminal 2 is connected B boost terminal 2. The increased voltage from B boost output terminal 3 and 4 is connected to the well-known D inverter terminal 1 and 2. D inverter R,S,T outputs go through the E RCD ring and connected to the F utility grid terminal R,S,T. A string terminal 1 connected to C1 stray capacitance while terminal 2 is connected to C2 stray capacitance while C1 nad C2 stray capacitance other terminal are connected to the ground (earth) potential. E RCD terminal 1 connects to H filter and G comparator terminal 1, while H filter terminal 2 connects to I modifier terminal 1. I modifier terminal 2 connects J controller terminal 2 while J controller terminal 1 connects to K PWM terminal 3. K PWM terminal 1 connects to B boost terminal 5 while K PWM terminal 2 connects to D inverter terminal 3.</p> |
