Volt Amp Consulting PPT Presentation

  1. 1. VOLT AMP CONSULTING, INC.<br />“There is design review………..<br />..and there is DESIGN REVIEW<br />Do your new <br />products benefit<br />from your current<br />design reviews………<br />or does thorough in-depth<br />analysis make sense for you? <br />
  2. 2. VOLT AMP CONSULTING, INC.<br />USE EXPENSIVE LITZ MAGNET WIRE?<br />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.<br />
  3. 3. VOLT AMP CONSULTING, INC.<br />Skin-effect currents at higher frequencies crowd into the thin outer skin<br />of magnet wire, causing increased power dissipation due to distributed resistance.<br />
  4. 4. VOLT AMP CONSULTING, INC.<br />Current can be seen during rapid negative excursions from positive value to<br />circulate within a winding: positive current continues flowing in the wire core,<br />yet negative current flows along its surface. While net current flow may be zero,<br />distributed current flows are quite high. <br />
  5. 5. VOLT AMP CONSULTING, INC.<br />Once high frequencies are no longer present, power dissipation behaves<br />identically in both single-wound and Litz wires. Where is the trade-off <br />between responsible thermal design, and product cost?<br />
  6. 6. VOLT AMP CONSULTING, INC.<br />Control loops can become difficult to analyze. We employ Signal Flow<br />Graphs and Mason’s Loop Rule on these occasions. The intuitive value of<br />These techniques have enabled us to retro-design existing power modules<br />To operate in parallel. Original module precision and accuracy was retained <br />At the system level, with no additional recalibration requirements.<br />
  7. 7. VOLT AMP CONSULTING, INC.<br />VAC’s policy is to fully document according to IEEE journal publication formatting standards<br />all its material contributions toward meeting your company’s goals. Reference is always a<br />short reach away, to re-examine methodology and premises. Future value is enhanced.<br />
  8. 8. VAC’s analysis capabilities extend to any subject which may be amenable to modeling with electrical analogs:<br /><ul><li>optimal heatsink extrusion to trade-off weight, size, duty cycle, and maximum temperature rise;
  9. 9. optimal cooling fan selection based on system airflow impedance at various operational altitudes;
  10. 10. Mathcad and MATLAB analysis of circuit meshes using Laplace variables
  11. 11. PSPICE simulation of AC, DC and Transient Response of circuits
  12. 12. Manual integral calculus for analytical form of solutions.</li></ul>VOLT AMP CONSULTING, INC.(800) volt-ampWWW.VOLTAMPCONSULTING.COM<br />
