Voltage Limit Unit (VLU) for DC Motor

Your problem is intristing for me. Could you write typical time diagram for gate of Q1,Q2,Q3,Q4 ? The aim of changing direction of motor at 50Hz is torque control or hold position or something else?

Hi, I am a post graduate power electronics engineer and having very good industrial experience of 8+ years in R&D and project development. I am excellent high frequency transformers design, circuits design, multi-channel LED Drivers, Regulated power supplies design with universal input to DC output, Audio amplifier, drives design, Filters design for harmonic analysis and Power factor correction, SMPS, LED drivers, DC-DC, AC-DC converters design, PFC interleaved boost converter, Battery management system, Battery chargers, UPS design, sine wave Inverters, solar grid tie inverters, Solar battery chargers and street light systems design from few watts to KW range using Buck, Boost, and Buck –boost, Interleaved boost/buck, Fly back Push Pull and H-bridge inverters. I have very good experience to design high voltage power supplies up to 50KV for capacitor charging power supplies using soft switching topologies. I have work experience to design from few watts to KW range meeting all compliances like EMI/EMC and safety standards UL etc.

Hello. I'm an electrical engineer / PCB designer. You may check my qualification in the profile. I'm interested in this task. Can you provide more details about it: what is power source? what para,etres of the motor? etc. We can discuss any details in the chat. Will do my best, Viktor

Hi, I have done similar Power Controls using High Speed PWM for Motor Control Application. Can you please share complete specification (Battery, Motor details etc) for the same. Thanks and Regards, Santosh

hello, I am an electrical engineer , I like to control electrical power by digital electronics , you are welcome to my profile to see samples of what I can do , I will try my best for u , but I still need to know more details about your project.

Greetings I have a lot of experience in designing electrical systems - specifically those involving H-Bridge DC Motor circuits (as provided) and could come up with a solution to your problem after some initial dialogue with you to more precisely define your requirements. I can either provide an analogue or digital electronics solution (or a combination thereof) in order to assist in limiting costs/provide greater functionality depending on the requirements. I can also do the full electrical design, PCB layout and any associated firmware that might be required if a digital solution is opted for (in order to incorporate additional functionality) and should be able to provide a solution quite quickly. Hope to hear from you soon. Kind regards, David

I have a low cost solution ready for your problem I can give Innovative, cost efficient solutions. I can build control systems. Can suggest Internet of things bases solutions to achieve different objectives.

I must learn this circuit's main aim and each units' specifications. Because i will select the optimal situation for your business. thank you.
