    Circuit Issue Help - Buck Converter with Type III Analog Voltage-Mode Controller

    Hello there! I am working on a buck converter (Input: 24 V, Output: 10 V) with gate driver circuit and type III analog voltage-mode controller. I am facing the issue wherein when I'm inputting around 12 V it outputs 9 V but then the current is also high (around 1.4 A). The duty is around 90%...

    Sequential Manual Switches with Logic Gates

    I am currently working on a project (Tesla Coil) and I built a very simple controller which connects to the neon sign transformer (NST). First there is a main switch which connects to the 120V mains and then a second "activate" switch which provides power to the NST. This is the current design...

    Toy Drone controller repairment

    hi everyone, I am trying to repair my drone controller. One of the component is broken and fell. I think its a crystal oscillator. Its 6mm x 1.5mm. I dont know how much mhz it is. Is there a way to know how much it is at home. I wil attach some images of it and where it belong. Even if you guess...

    Motor Controller Mystery

    I have been working on an Electro-Arc tap burner in the machine shop. The power feed mechanism only works partially, as the feed-rate potentiometer seems to have no effect on the actual speed of the motor. We confirmed the potentiometer to be in working order so I believe there is a fault...

    Charging individual 3.7V Li-Ion batteries that are connected in series to from 7.4v supply

    Hope you all are staying safe and healthy. The Pandemic lockdown has forced us to work with the only components we have at home. I am working on a battery-operated esp32 pico board having other sensors hooked up to it that need 5v of supply. So I connected two rechargeable 3.7v Li-Ion batteries...

    Extend wireless connection range with Sony PS2 controller

    I am coming up with a project - Robotic arm rover by using Arduino. I decided to use a PS2 controller to control and send command. The wireless connection range is around 10 m. Is there any way to work around so that the wireless range can be boost up to 300 m at least? Is there any add on...

    Need advice on making a heated pad for my cat

    Would it be possible to make my own small heat pad that would work with a 120v Sunbeam electric blanket controller? It's 180W style M85AP. I don't believe I have any nichrome wire, just some solid copper wire in a couple different gauges. Not sure if that would work or not so any advice would be...

    Embedded Derivative Control for DC motor speed

    Hi all, I am fairly new to embedded control systems, for which I am using a PSoC 5LP to implement closed-loop speed control. I am currently working out the code for the PID controller and this is the following code I have (in C): P = Kp*error; I +=ki*error; D=Kd(error-last); PID=P+I+D; Now, I...

    LCL Filter Plant Control

    Hi everyone! I don't know if this is the place to ask Control Theory related questions, but it's for modelling a power electronics circuit so I thought I could at least try. I have to design a grid connected inverter in Simulink using the PLECS toolbox and I ran into some problems when designing...
