High Current Voltage Regulator Using Mosfet
High Current Voltage Regulator Using Mosfet. According to datasheet lt1038 has following properties. The required voltage is selected by a rotary switch down the stack of zeners.

This setting adjusts the base current for the bf337 which in turn restricts the main transistor bf458s voltage and current flow to the output. So simple, in fact, that adding pwm input support almost doubles the parts count! It acts as an electronic switch.
Regulator Will Primarily Supply Transmitter Osc And Power Amp Screen.
Hello, when you want to use the lm317 as regulator, you will get a max of about 10 volts on the output as the lm317 needs some voltage to regulate. At 150ma its already sagged to. This version is similar, but uses a power mosfet instead of a bipolar power transistor.
The Datasheet For It Can Be Found Here.
Datasheet here r2 represents the esr of my power supply. It is good quality, excellent performance and durable with pcb. For use in electronic telecommunication, high power radio transmitter, etc.
Presenting, The Power Mosfet Linear Current Regulator, Inspired By And Based On The Instructables Post Circuits For Using High Power Led's By Dan.
But what i've read, it seems like a mosfet can regulate both voltage and current by taking the input voltage and current, then using voltage to increase the current, so the output will be a lower voltage but higher current. It can give the output current 20a or 400watts and can adjust the voltage of 4 to 20v—or apply to 0 to 30v easily. In addition to excellent load and line regulations, lt1038 is fully protected by current limiting, safe area protection, and thermal shutdown.
The Channel Resistance Is Very High So The Transistor Acts Like An Open Circuit And No Current Flows Through The Channel.
Advantages of using mosfet instead of bjt is it does not have the problem of second. Again, both mosfets must withstand the full rail voltage. The transistor allows you to control a circuit that’s carrying higher current and voltage from the a lower voltage and current.
Sure I Cannot, It Is Obvious :) Simply Use Mosfet As Current Regulator Is Waste Of Heat And Energy $) For My Charger Purpose Is Enough To Regulate Voltage And Sens Current, So Current Limiting Will Be Done By Arduino.
Originally based on a series tube, i also gave circuit details for use with an enhancement mode mosfet. However, designing with these devices is not as The required voltage is selected by a rotary switch down the stack of zeners.
