How to increase output voltage of a Transformer?

by stepping up process or by increasing the turns ratio

By increasing the output/secondary turns and increase the input voltage.if you put diode capasitor to the output of transformer the voltage will increase 1.41x voltge output DC

Increase the Wire Turns of the transformer which will increase its Voltage.

V1/V2=N1/N2 SO BY INCREASE SECONDARY TURNS  IN OUTPUT WILL INCREASE VOLTAGE OUTPUT .OR DECREASE THE TURNES ON PRIMIRY COIL 

BY CHANGE THE STEP IN TAP CHANGER (VOLTAGE REGULATORE ) IN PERIMIRY COIL IT CAN INCREASE OUTPUT VOLTAGE AS DATA SHEET .

2 - INCRESE VOLTAGE SOURCE INPUT VOLTAGE 

By using step-up transformer

we can increase the output voltage by just increasing the number of turns of the seccondary coil in the transformer.

by increasing turn ratio of secondary wire with respect to primary wire of transformer, commonly known as step up transformer

V1/V2= N1/N2 to increase the secondry side turn ratio, ouput can be increased

There are at least 3 alternatives way to increase Vout of the transformer;1. Re-coil the secondary winding. Increase the number of coil turns.2. Disconnect pin CT type. 3. Combine 2 transformer become 1.

To increase the output voltage of a transformer the secondary coil turnes should be more than the primary coil turns (the output voltage will be higher than the input voltage)

To increase number of turns of coil
