Solar panel circuit stability
PV voltage corresponds to open-circuit voltage (Nser*Voc=5*64.2=321 V, see Vmean trace on PV scope). The three-level bridge operates as a diode rectifier and DC link capacitors are charged above 500 V (see Vmean trace on VSC scope ). At t=0.05 sec, Boost and VSC converters are de-blocked. DC link voltage is regulated at Vdc=500V. - Download [PDF]
