What are Step-up and Step-down Transformers? This is a very useful device, indeed. With it, we can easily multiply or divide voltage and current in AC circuits. Indeed, the transformer has made the long-distance transmission of electric power a practical reality, as AC voltage can be “s...
A transformer is a static electrical device, used to transfer the energy in electrical form between two or number of circuits. The main function of a transformer is to change the alternating current from one voltage to another voltage. The transformer doesn’t have any moving parts and works o...

There is an internal 5M pull-down resistor on this pin. If not used, this pin can be left open or grounded. C1 (Pin 10/Pin 13): Input to the Charge Pump and Rectifier Circuit. Connect a capacitor from this pin to the secondary winding of the step-up transformer. C2 (Pin 11/Pin ...
In this paper, a high step-up three-level DC–DC converter with a symmetric structure for PV application is proposed. The converter has high voltage gain. This is achieved due to the use of two high step-up cells and two resonant paths in its structure.

(Selecting R1 And R2) Referring to the adjustable regulator in Figure 17, the output voltage is programmed by the resistors R1 and R2 by the following formula: VOUT = VREF (1 + R1/R2) where VREF = 1.23V (1) Resistors R1 and R2 divide the output voltage down so that it can be ...
The voltage gain ratio can reach up to 15 times, while no transformer or coupled inductor has been used. This high step-up capability is achieved by using two high step-up cells and two resonant paths in the converter topology. The converter has low input current ripple. Moreover, the ...
