HOW TO DOUBLE TRANSFORMER VOLTAGE

A circuit to double or step up the output of a small transformer so that it can power high voltage circuits. High voltages are at times needed but its a problem when we have to spend huge sums of money before we accomplish it.

Am going to show you a high current circuit which can double or even triple the output of any transformer connected to it. The circuit can be used as car battery chargers, inverter battery chargers and as a regular power supply.

CIRCUIT OPERATION

When transformer T1 receives and input voltage, it produces stepped down AC output onto the mosfet.

The mosfets Q1,Q2,Q7,Q5 are connected as high current diodes that's why the gates are connected to their sources.  This mosfets rectify the AC  onto the filter capacitors C1 and C2 where boosting takes place because of the charging action of the capacitors.

 

CIRCUIT APPLICATION 

This circuit can be used for high voltage power supply's, battery chargers and any application where small transformers are required to produce doubled or tripled voltage
