Abstract: |
A unique high efficiency photovoltaic (PV)
system is presented. It uses partial sine wave tracking for a
pulse-width modulation (PWM) boost converter as well as
a full-bridge inverter. The boost converter and full-bridge
inverter are connected via a compact intermediate film
capacitor (i.e. non-smoothing DC link stage). PWM
switching is activated by a dual mode control technique. In
the proposed topology, simultaneous switching of both
power conversion stages is avoided and therefore this
increases the power conversion efficiency. The distinctive
operating principles of these two power processing stages
are discussed and analyzed with the experimental results
for single-phase loading of the PV system. |
