A new thermal model generation capability has recently been provided in Simcenter Flotherm. It will not only improve the accuracy and efficacy of the electro-thermal design process, but will also be easy for electronic circuit designers to use. In this article, which is Part 2 of a series, I’ll focus on an “LED Spotlight” application. This is intended to represent systems that are primarily composed of continuous (non-switching) analog electronics devices.

Solar energy systems for residential use are typically limited by code to 600V, but commercial installations can operate at higher voltages. This opens the door to more efficient energy utilization. Achieving that efficiency has been made easier with the introduction of Silicon Carbide (SiC) Power Devices from Rohm Semiconductor. These components offer significant performance advantages over their Silicon (Si) counterparts.

Press the shift key as you click on a portion of the wire. This will select the entire wire which can be deleted with the delete key.

Yes, by pressing either the shift or control keys while you click and drag with the mouse. The shift key will add the enclosed items to the currently selected set. The control key will clear whatever is currently selected and select the enclosed items.

Holding the shift key down while clicking on an object will add this object to the selected set. Holding the control key down while clicking on an object will toggle that object’s selection without changing anything else that is selected. If the object was selected, it will be deselected after you click with the control key pressed.

VHDL-AMS and SPICE. SystemVision Cloud doesn’t provide support and/or compatibility for several proprietary constructs found in some PSpice® or LTspice® models.

That is an Intercom chat button where you can chat with a SystemVision Cloud developer.

To prevent other users from seeing a design, it must be stored in a secret group which requires a subscription.  Refer to the Plans and Features section of the home page for more information.

No. With a free account you can create as many public designs as you want.

Overview Groups are a new hub for collaboration. Our group framework provides a flexible, dynamic environment for users to engage in novel ways both with teammates and customers. Within a group, users have the ability to share and collaborate on designs and discussion boards, store relevant files, and more. There are public, closed, and secret groups. Creating and joining public and closed groups is free with any account, while secret groups require an Innovator level or higher subscription . Group Search From the 'Groups' tab, click 'Browse Groups' to see all public and closed groups. You can

In my previous article I demonstrated an important self-protection feature of the NCV84160 from ON Semiconductor; its ability to enter thermal limit cycling if the internal device temperature gets too high. My friend and fellow model-developer, Alain Stas of Vishay, recently suggested that NTC thermistors could be used to provide similar protection at the circuit board or system level. One application where this could be implemented in a very natural way is for LED lighting systems.
