A NEW TOPOLOGY SINGLE PHASE INVERTER BASED ON MODIFIED BUCK-BOOST CELL
This study proposes a single-phase full-bridge inverter topology based on modified buck-boost cells that can solve the common-mode problem. This common-mode voltage causes leakage current to flow due to the capacitance between the positive and negative points of the source relative to ground....

| Summary: | This study proposes a single-phase full-bridge inverter topology based on
modified buck-boost cells that can solve the common-mode problem. This
common-mode voltage causes leakage current to flow due to the capacitance
between the positive and negative points of the source relative to ground. The openloop control method with bipolar and unipolar Pulse-width modulation (PWM)
switching pattern is used and the hysteresis current control method is used for
closed-loop control. The simulation results of the output voltage, output current,
and common-mode voltage of the proposed inverter are presented. Experiments
have also been successfully carried out to verify the simulation results, the output
voltage and current are quite sinusoidal with a small total harmonic distortion
(THD) and common-mode voltage ripple occurs at low frequencies, a comparison
with a single-phase full-bridge inverter using an LC filter was also carried out |
