| Summary: | Renewable energy has become very important in generating electricity for the
energy transition, as high air pollution is a classic energy problem. Transition
energy moves from conventional energy to clean energy, such as photovoltaics
(PV). In the field of photovoltaics, an inverter is needed to convert the DC voltage
(direct current) of solar panels into the AC voltage (alternating current) required
to supply the load. In the conventional H-bridge inverter topology, the inverter has
some disadvantages, such as the voltage is not sinusoidal but instead is a switched
DC voltage and high common-mode voltage. Common-mode voltage can cause
significant capacitive current leakage, which can cause undesirable operation in
solar applications. The common solution for these situations is to add a large filter
to the input or output of a conventional inverter. This paper proposes an inherent
sinusoidal voltage source inverter based on a modified Cuk cell, which
simultaneously produces a lower sinusoidal output voltage and common mode
voltage. The proposed topology requires no additional input or output filters;
Analytical expressions are drawn to confirm the operation. Simulation results were
performed to confirm the mathematical analysis. The laboratory performed the test
results to verify the proposed inverter. |
