Dc Electronic Load Circuit Schematic. We will also upgrade the software to allow for input entry via the keypad as well as the rotary encoder. One is to control the mosfet and the other one is to amplify the sensed current.
I have designed the circuit to use a logic level mosfet irl540n t1 so that we can power the circuit from a voltage much smaller than 9v. Experiment with an electronics kit. In part 4 of this project on the electronic dc load we are going to add a remote voltage sense circuit increase the power capacity by adding additional power mosfets and build the completed unit into a metal project case.
Multiply the supply voltage with 1 kw to get the value of r1.
One is to control the mosfet and the other one is to amplify the sensed current. The advantage of such a dc load is that you can understand how it works modify or repair it if necessary far easier than you would with. The value of resistor r1 is dependent on the supply voltage. One is to control the mosfet and the other one is to amplify the sensed current.
