How a transformer is used in a PV inverter?
To step up the output voltage of the inverter to such levels, a transformer is employed at its output. This facilitates further interconnections within the PV system before supplying power to the grid. The paper sets out various parameters associated with such transformers and the key performance indicators to be considered.
What happens if a transformer is switched on at an instant?
If the transformer is switched ON at an instant when the instantaneous value of applied voltage is at its positive peak, then the ux would rise from its natural zero value up to +Φm during the next quarter cycle (Magnetizing lags voltage by 90deg).
Should a three-winding transformer have an electrostatic shield?
For example, in the stacked windings arrangements of the three-winding transformer, it is recommended that the electrostatic shield be constructed in two separate parts (top and bottom) in order to avoid additional eddy losses and abnormal temperatures in the situation of the unbalanced loads between two inverters.
How does proximity effect affect transformer windings?
Transformer windings are affected by Proximity Effect: effect of reduced “effective” area due to this effect, similar to Skin Effect, is proportional to frequency, so for higher order harmonics the AC resistance of winding conductors will be further increased, i.e., added losses.
Why are inverter manufacturers supplying nished Integrated Products?
With a plethora of inverter station solutions in the market, inverter manufacturers are increasingly supplying the consumer with nished integrated products, often unaware of system design, local regulations and various industry practices.
What if the harmonic current owing through a transformer exceeds design limits?
When the harmonic current owing through the transformer exceeds the design level of 5% of the rated current, the heating effect in the transformer should be evaluated by applying the methodology contained in IEEE C57.110-1998. This evaluation will ensure that the transformer insulation is not stressed beyond design limits.
