Volt Amp Consulting offers design review and analysis services for companies using expensive Litz magnet wire. They suggest that a company's tradition of using Litz wire may no longer be necessary with modern product designs and could unnecessarily increase costs. Volt Amp uses techniques like signal flow graphs and Mason's loop rule to analyze control loops and can retrofit existing power modules to operate in parallel while maintaining precision. They fully document their work and have expertise in modeling and simulation across various domains to optimize aspects like heatsink design based on factors such as weight, temperature, and altitude.

1. VOLT AMP CONSULTING, INC. “There is design review……….. ..and there is DESIGN REVIEW” Do your new products benefit from your current design reviews……… or does thorough in-depth analysis make sense for you?

2. VOLT AMP CONSULTING, INC. USE EXPENSIVE LITZ MAGNET WIRE? Your company’s tradition may not be serving its best interests today. A marginal design may have necessitated use of expensive Litz wire at one time, yet products today may unnecessarily shoulder the cost burden of this tradition.

3. VOLT AMP CONSULTING, INC. Skin-effect currents at higher frequencies crowd into the thin outer skin of magnet wire, causing increased power dissipation due to distributed resistance.

4. VOLT AMP CONSULTING, INC. Current can be seen during rapid negative excursions from positive value to circulate within a winding: positive current continues flowing in the wire core, yet negative current flows along its surface. Net current flow may be zero while distributed current flows still remain quite high.

5. VOLT AMP CONSULTING, INC. Once high frequencies are no longer present, power dissipation behaves identically in both single-wound and Litz wires. Where is the trade-off between responsible thermal design, and product cost?

6. VOLT AMP CONSULTING, INC. Control loops can become difficult to analyze. We employ Signal Flow Graphs and Mason’s Loop Rule on these occasions. The intuitive value of these techniques have enabled us to retro-design existing power modules to operate in parallel. Original module precision and accuracy was retained at the system level, with no additional recalibration requirements.

7. VOLT AMP CONSULTING, INC. VAC’s policy is to fully document according to IEEE journal publication formatting standards all its material contributions toward meeting your company’s goals. Reference is always a short reach away, to re-examine methodology and premises. Future value is enhanced.
