How to filter the voltage?
To smooth this tensionwe use a capacitor of filtering which ensures a reserve of energy when the tension from the Graetz bridge becomes weak. It is then he who supplies the circuit alone. Opposite, the diagram of the recovery of the tension with the Graetz bridge and the capacitor of filtering.
The greater the capacity of capacitor is large, the more it will smooth the tension. We can see it on the graph: the curve in red is smoothed with a capacitor having a weaker capacity than the blue curve.
the capacitor of filtering connects in parallel with the load resistor. It must be able to withstand between its terminals a DC voltage at least equal to the maximum output voltage. The other types of circuits filtering are much less used than filtered capacitive.
A UPS is a box that connects to the mains. It allows the protection of connected electronic devices and the correction of electrical disturbances in the network by means of a voltage regulator. It is capable of supplying your equipment with a stable electric current even when the voltage increases or decreases.
As it changes depending on the weather outside, his job is to find it and adapt to it. Now you know that the operation of the inverter comes down to converting the electric current and that it seeks the best optimization for your solar installation.
The mission of the inverter does not stop at power conversion. It is much more useful than that. How ? Well, he is looking for the best operating point of the solar installation. Let me explain. A solar system produces current, so far nothing very complicated.
We generally speak of ripple rate, when comparing on a DIRECT current, the percentage of ALTERNATING ripple compared to the total of this current. For example on a DC voltage of 10 v, if we find a residual ripple of 1 volt this gives a ripple rate of 10% (1/10 of the voltage).
