Technical FAQs 4

Why do PV inverters need a boost circuit?

Consequently, inverters need to have the ability to boost the output voltage of PV in order to maintain a stable AC voltage for the load. The traditional voltage source inverter is a step-down inverter. When the input voltage is low, the traditional voltage source inverter is usually added a DC-DC boost circuit at its front stage.

How can a boost inverter achieve a higher voltage gain?

First, a new boost inverter without inductors is put forward. Second, a corresponding modulation strategy is proposed to achieve capacitor voltage self-balancing and to regulate the output voltage. Third, a new scheme is given to extend the inverter and obtain a higher voltage gain. The remainder of this paper is organized as follows.

How does a boost inverter work?

The boost inverter can be derived from a boost converter and a full bridge inverter by multiplexing the switch of basic boost converter. On boost converter side, the dc boost inductor is replaced by a switched inductor concept which can increase the output voltage and hence gain & efficiency.

Can a transformerless boost inverter work in a wide input voltage range?

Conclusion A switched inductor based transformerless boost inverter is proposed in this paper, which can work in a wide input voltage range. The boost inverter can be derived from a boost converter and a full bridge inverter by multiplexing the switch of basic boost converter.
