Mosfet Voltage Regulator Schematic. W 230 v supply 202 v. Hello aytac it is a shunt regulator meaning the excess voltage will be grounded by the mosfet so your 24v will grounded until it becomes 12 v this will make the mosfet very hot you must use large heatsink on the mosfet.
Mosfet power 9 45w w 100ma load power 20 w conservative for scenario 1 requirement w 230v supply. However the readily available enhancement mode mosfets like the dn2540 have limited short. T reg revised mosfet based high voltage regulators for tube amps.
T reg revised mosfet based high voltage regulators for tube amps.
The threshold voltage of power mosfet s can be 3 to 5 volts with usual devices and still above 1 volt for those logic ones. Hello aytac it is a shunt regulator meaning the excess voltage will be grounded by the mosfet so your 24v will grounded until it becomes 12 v this will make the mosfet very hot you must use large heatsink on the mosfet. However the readily available enhancement mode mosfets like the dn2540 have limited short. Originally based on a series tube i also gave circuit details for use with an enhancement mode mosfet.
