Bob Arnold - 10/06/00 18:48:23 My Email:robert.arnold@chamberlaingroup.com | Comments: I used your PCB trace width calculator. Intutively I would say the required internal trace width would be less than the external case since the external trace can peal off; the opposite is true according to the calculator???? Why? (In air, the external layers have better heat transfer. The internal layers are blanketed by a good heat insulator, so they get hotter. In vacuum, I use the internal layer guidelines. B. Suppanz 1/8/01) |

Chris Marshall - 08/17/00 21:30:36 My Email:chris.marshall@usahq.unitedspacealliance.com | Comments: Very nice website. I just started laying out circuit boards. We are using a circuit board cutter to make our boards. Now what does temperature rise mean and how does it apply? (Temperature rise means how much hotter the trace will get with current flowing in it compared to without. You have to decide how much temperature rise your board can handle based on the operating environment and the type of PWB material used. Ten degrees is a very safe starting point. B. Suppanz 1/8/01) |

I believe on thermal o/l. Please comment. Thanks (SMPS, or Switched Mode Power Supplies, are more efficient than Linear Mode Power Supplies. This allows either more power in a given volume, a smaller supply, or cooler and therefore more reliable operation. The main disadvantages of SMPS's are cost and switching noise. B. Suppanz 1/8/01) |

I've got to make a current mode PSU work over an 11V to 80V input range, it's not easy, especially over a horrific temperature range. Any info I find on the web I'm grateful for. Thanks Dave White. |

Do you know of anyone doing work or research on control loops for a class D power circuit driving a tuned RLC circuit? I can find literature on DC outputs, but none on AC outputs. Thanks! |

I have been lookin for a long time for any info to build a switched power supply mainly what to do about the x-former ie number of turns, wi e gauge ect. Well I'm on my way to check this place out. thanks....best regards, Steve |

Ernst Bucher - 08/18/98 12:59:01 My Email:ebucher@ktron.ch | Comments: Great site!! Does anybody know where to get more information about SMPS-design for low power (1..5 W)and with a transformer (because of galvanic isolation 2500 VAC). Design should be as simple as possible, load regulation is not very important. Thanks!!! Thanks |

This could be a good approach for the controller sceme. Currently we are working with optimal controlled scheme realized in a SP from Texas Instruments. Have You some experience with this controller technique? Best regards WF |
