H-Bridge only low output voltage; IRLZ-34N
I want to create a LED driver with the help of an H-Bridge. I have some experience with the IRLZ-34N and already created some simple inverter driver boards with it.
But this circuit is giving me a ...

What are the limitations of AC coupling a MOSFET gate?
I came up with this AC coupled half bridge for high positive and negative voltage output with logic level control that I cannot find in any resources about (probably due to wrong search terms):
It ...

Driving a Peltier Module via N-channel MOSFET H-Bridge
I'm working on a circuit to control a heating/cooling element (Peltier module) using an H-bridge. I'm using FDP8447L for that purpose. My Peltier is rated for 6 amps current and 15.4 Volts. The gate ...

How to analyze this MOSFET H-bridge circuit?
In my university electronics course project, I am asked to analyze an H-bridge circuit. It is a simple H-bridge in which the motor is represented with a 37 ohm resistor and thus has no diodes.
The ...

Why it is preferred to use PNP and PMOS for pull-up, and use NPN and NMOS for pull-down
I have noticed that when I was designing universal logic gates like CMOS NOR gate that uses PMOS for pull-up and NMOS for pull-down.
Then I faced it for second time with
the H-bridge circuit, but ...

High side N channel gate driver
So I realized with the suggestion in the comments that there is a much better solution to driving a higher voltage H bridge than using transistors or secondary mosfets and zener voltage. I have ...

Half Bridge with dual powre supply and two N-channel Mosfets?
I wanted to ask (can't find a straight answer) if it is possible to make a half bridge with two N-channel MOSFETs (I have the solution with one nmos and one pmos, but I'd like two nmos).
For the ...

N-MOSFET switching an H-bridge: problems with PWM
In this circuit an Arduino digital pin drives the Gate of a N-MOSFET. When the pin is HIGH, current can flow from the H-Bridge GND to board GND. When it's LOW, current can't flow. What I need is to ...

Using p-channel mosfet on high side of h-bridge, do I really need a driver chip?
I know there are fancy h-bridge ic's to drive high side of h-bridge but I guess that is when I have to drive n channel mosfet.
I am planning on using p channel mosfets on high side and n channel ttl ...
