Evaluate electronic circuit design

Job ID: 37476299

Budget: $30 – $250 USD

Project Title: Evaluate Analog Electronic Circuit Design

I am looking for an experienced professional to check / evaluate the design of an analog electronic circuit.

What I need is a professional opinion of circuit design attached.
The prototypes provided do not work at all, so I am wondering is it a design or implementation issue?

The circuit meant to be a current limiter that would work up to 600V DC and up to 20amps and be able to limit current between 0 and 20 amps regardless the voltage, so with the utilization of a potential-meter the user could regulate the current .

Specific Requirements:
- Evaluate the overall design of the analog electronic circuit
- Provide a high level overview of the circuit design

Ideal Skills and Experience:
- Extensive knowledge and experience in analog electronic circuit design
- Strong understanding of electronic components and their functionality
- Ability to provide a high level overview of circuit designs

Please note that this project does not require a detailed analysis or component-level breakdown. The focus is on evaluating the overall design and providing a high level overview in the evaluation report.
