Snubber Design for SMPS Circuit

Job ID: 38745402

Budget: ₹600 – ₹1,500 INR

I'm in need of an Electronics Engineer with a strong focus on power electronics, specifically in AC to DC conversion (SMPS). The primary purpose of this project is to develop a snubber and RCD clamping circuit for the MOSFET situated on the primary (hot) side of a pre-existing transformer in my SMPS. The input is 100 VAC - 260 VAC converting to 24 VDC at 4A.

Current Issue:
- The main challenge I'm facing is voltage spikes that are causing the MOSFET to fail.

Ideal Candidate:
- Extensive knowledge and experience in power electronics and circuit design
- Proven track record in designing and troubleshooting SMPS
- Expert in the use of the UC3843 controller
- Proficient in using LTspice for design validation

Your Responsibilities:
- Create a robust snubber and RCD circuit
- Validate the design with the SMPS board that we have available
- Utilize EasyEDA Pro for design sharing

Requirements:
- Primary side input: 100 VAC - 260 VAC
- Target: Secondary side output of 24 VDC (4A)
- Limit Vds to less than 700 V at peak load

Skills and tools proficiency will be key to the success of this project. I'm looking forward to collaborating with a talented engineer who can solve this pressing issue.
