#26 🚀 I don´t optimize magnetics, I optimize...

The Newsletter of High Frequency folks

👋 Hello! Dr. Molina here! 👨‍🔧

Power electronics engineers use the verb “Optimize” referred to magnetics to optimize:

• Efficiency

• Cost

• Volume

• Weight

However, instead of just focusing on these factors, I optimize the COMPLETE PROCESS… which means…

• 📝 Design Stage

• 📦 BOM selection

• 🛠 Tooling decisions

• 🚢 Production logistics

The main reason is, that we have discovered after some years of failing in the optimization, that was following an academic optimization, not an industrial optimization.

📝 The cost of the design phase is related to the engineering hours. Usually takes between 100-1000 hours of engineering, depending on the number of iterations. The impact on the final cost depends on the accuracy of your design.

📦 The BOM selection for a MOQ of 1000 units, can have an impact on the final unitary cost of 500%. If you select a material that is located in East China, the cost is infinite, because you are losing your customer.

🛠 The tooling creation is an art. If you optimize the design, to be manufactured easily by known toolings, you can save up to $20k in total. Special toolings are very expensive and the manufacturer will charge you the cost of each unit.

🚢 The logistics:

• Cores in China (100 kg),

• Coils in Poland (10 kg),

• Wires in the UK (300 kg),

• winding factory in Taiwan

• Final destination: Minessota (USA).

Make your numbers.

Conclusion:

First, review off-the-shelf components before customizing your design. We are building a library of great off-the-shelf designs. If you don´t find it, design with all the previous aspects in your mind.

By the way, today we are starting a Training where you can use our online simulator for one month and learn about Process Optimization.

❌ If you like to optimize only losses, Frenetic is not appropriate for you.

✅ If you want to optimize the complete process, You are Frenetic.
