Technical Note #1 - Expanded Control Element Exercise. This is an expanded version of Intermediate Exercise 10: Control Elements. These topics are covered:
- Thermostat-style control of wattage.
- Thermostat-style control of ambients. This allows you to simulate the effect of a fan which turns on at elevated temperatures.
- ΔT control elements. Most commonly, these are used to create a negative heat source, which is useful when working with thermoelectric coolers and liquid cooling systems.
- Proportional control elements.
- Stability issues when creating and modeling thermal control.
Technical Note #2 - Changing The Thickness Of An Internal Copper Layer. It's easy to change the weight of an outer copper layer in a circuit board stackup. But it's a bit more difficult to modify the weight of an internal layer. This technical note provides a step-by-step method for modifying internal layers. Once you learn the procedure, you can perform the weight modification in just a couple of minutes.
Technical Note #3 - Using Special DPAK's For Preliminary Modeling. The special DPAK is the simplest type of enhanced source. As such, it's particularly useful for preliminary modeling. This technical note provides an example of using a special DPAK. Also, a comparison is made between a model with a special DPAK and a model with a more detailed enhanced source.
Technical Note #8 - Quasi Steady State Transient. This technical note explains a highly efficient method for handling duty cycles which consist of a long period of on/off cycling, followed by several long duration pulses. To understand more, just click on the link and look at the picture on the first page. Sauna Modeling System is required to use the techniques explained in this technical note.
