Consider an electrolisys aplication. The plates and electrolyte form a capacitor. In the begining, the electrolyte is cold and conducts less requiring higher voltage to push current through. Then as the electrolyte warms it becomes less resistive and conducts more current. Annunregulated buck converter dops in voltage with a higher current draw. And with electrolisys, lower voltage end up drawing less current and produces hydrogen more efficently. The current voltage responce us more like a zener diode and resistor than a simple resistor. This loosely uses current to warm up the electrolyte making it more conductive so that it can pull more a little more current at a lower more efficent HHO generating voltage. It loosly self regulates the current without feedback circuitry. An adjusable pwm circuit can may be more interested in lowing the duty cycle with feedback from a temperature sensor to further regulate how much current goes through the cell by lowering the outut voltage further, thus controlling the watts consumed by the HHO cell and further improve efficency.

Hello, maybe I still make something wrong. There is a schematic at 8:28. You use IRFZ44N. It's an N-Channel, but you use a P-Channel symbol. Another is the value of L and C. The value of L can not be compatible with 100UF E-Cap.

Dedicated IC's have protection circuitry but I read that the often used Maxim 1771 has a poor design because the gate of the Mosfet is pulled to ground by a resistor: quote "a substantiol amount of power is wasted in the FET" But I need to look into that much more... I want a safe PS so I can leave a home made HV PS safely on 24/7.

This is a good video and I don't want to have to critisise here buuuuuuuuuuut ... I don't see how the circuit at 8:28 could work, or at least work well. I know how a buck converter works, but it's the way the mosfet gate is being driven here that is getting at me. Surely like this the gate won't get a good square wave and instead will be more of a ramp wave because of the mosfet gate capacitance, right? And wouldn't that get even worse with more load due to the miller effect? And also, having an n-channel mosfet connected like this, surely the gate voltage could never get high enough to turn the gate fully on so the mosfet will be in it's linear region? Also it's drawn here as a p-channel mosfet where as an IRFZ44N is n-channel.
@wdujsub7902
6 жыл бұрын
Yes there is a N- channel mosfet and there should have been a P channel just like you said. If you put a N channel like that it will be mostly closed or just very slightly opened. Well the miller effect is really a problem only in case of transistors used as amplifiers, since it changes the input and output impedances slightly and can limit the frequency range of the amplifier, but in case of switching transistors it shouldn´t be a problem. The gate doesn´t get the same square wave as it comes out from arduino, but it is a lot sharper that you might think, to make it ever sharper I would decrease the value of the 10k resistor to maybe 2-3k depending on the datasheet of the bipolar transistor. But because of the approx. 33kHz frequency the mosfet operates on it is low enough to make sharpness of the edges more than sufficient to fully open and close the transistor (at least my oscilloscope says that :) ) hope that helped. if you want to correct me on something please go on :)

A very fundamental property of an inductor is that you cannot instantaneously change the current through one. When the switch is ON, current flows from the input supply through the inductor. When you turn the switch OFF, the inductor "tries" to make the same current that was flowing just before that continue to flow. The voltage across the inductor will rise to whatever magnitude is required to make that current flow. That voltage could be a few millivolts if there were a low-resistance path or it could be thousands of volts if the only path available were very high resistance. (with practical, real inductors you usually don't get extremely high voltage because there is enough capacitance between the turns of the windings). The very high voltage can easily destroy a semiconductor switch. With a mechanical switch the high voltage would cause an arc across the opening contacts. In order for the current to continue to flow in the same direction in the inductor itself, the voltage across the inductor changes polarity. One way to understand this is to draw a simple circuit with a battery, an inductor and a resistor in series. If you "instantly" replace the battery with a short circuit and keep in mind that the same current continues to flow at that instant, you'll see that the voltage across the inductor must now be the opposite of what it was with the battery in the circuit. In the circuit as it is shown in the video, the diode makes the path that allows the current to continue to flow, transferring the energy stored in the inductor to the capacitor and the load. One thing that helps in understanding how these circuits work is to consider the output capacitor voltage to be constant during any single switch cycle. In reality the capacitor voltage does rise a little bit, but normally the circuit is designed so the rise is very, very small relative to the average voltage on the capacitor when the circuit is operating normally. Of course when you first start the circuit the capacitor voltage is slowly raised over many switching cycles.

yeah some mosfets gates have a minimum voltage required to turn them on that is higher than the 5 volts an arduino pwm pin can manage to put out. For this you need a separate power source that is high enough to match that gate threshhold voltage - a lot of power n-channel mosfets have a gate threshhold voltage of 20 volts. You need the arduino to control another mosfet that turns on from only 5v and that mosfet will turn on the power supply to the big power mosfet which will turn the big power mosfet on. So you need that middle man mosfet to make things work.
