Solar Micro-Inverter Simulation
Solar inverter simulation was done using PLECS, power electronics circuits simulation software. This inverter uses a lookup table to generate variable voltage inputs. Variable input is used as a input to the DC-DC converter stage. This configuration uses a flyback DC-DC converter. DC-DC converter converts variable input to a steady 200V output. Steady 200V is used as the input to the DC-AC stage.

Figure 2: Full bridge Bipolar Inverter
DC-AC stage uses a full bridge bipolar inverter to generate 120Vrms sinusoidal voltage in phase with grid voltage.
