Abstract:
This paper presents a generalized cascaded multilevel photovoltaic inverter topology for grid connected PV systems with hybrid phase disposition PWM control scheme. Hybrid PWM strategy based on the combination of fundamental frequency PWM and high frequency phase disposition PWM which reduces the power losses and improves energy efficiency.

PERFORMANCE ANALYSIS OF MULTI LEVEL INVERTER TOPOLOGY FOR PV CELL APPLICATION
PROBLEM IDENTIFICATION- The output of the PV cell is generally not continuous through out the day due to unstable solar radiation.
- Traditional inverter harmonics and size of the filter is large.
OBJECTIVE- To analyze the multi level inverter with proportional integral current control algorithm for grid connected PV System to avoid unstable solar radiation.
