Technical FAQs 4

What is a photovoltaic DC-DC converter?

Photovoltaic DC-DC converters are a crucial part of PV power conversion. The DC-DC converter is provided to regulate the constant output under various operating conditions of photovoltaic cells. Bourns offers large portfolio of high voltage circuit protection and circuit conditioning (Magnetic) devices to meet the needs of PV DC-DC designers.

Why do solar PV modules need a DC-DC converter?

The major issue of solar PV modules is low supply voltage which is increased by introducing the wide input voltage DC-DC converter. The merits of this introduced converter are low-level voltage stress on diodes, good quality supply power, high voltage gain, plus low implementation cost.

What is a DC-DC converter?

Therefore, a DC-DC converter employing some MPPT algorithm is generally used as a front-end converter to efficiently extract the PV output power and convert the PV output voltage to a high voltage DC-BUS. Depending on the system requirement, the DC-DC converter can use either an isolated power stage or a nonisolated stage.

How does a DC-AC inverter work?

The DC-AC inverter transfers the power from the DC-DC stage to an emulated grid connected across its own output. A C2000TM PiccoloTM-B control card and a 500-W isolated DC-DC stage EVM are used to implement the complete DC-DC system. This EVM comes with a Piccolo-B control card and not the Piccolo-A card.
