Product Portfolio dialog box comes up when "Create New Design" is started.
The "Help Me Choose" feature facilitates PI product selection process and provides the best way to achieve the desired parameters of your future Power Supply design.
Product Filter section allows you to filter families in the tree by selected parameters:
Application type - select the application area where you want to use your power supply (mandatory filter to use Help Me Choose)
Total PO - range of total output power (mandatory filter to use Help Me Choose)
Input type - input voltage range:
# of outputs - number of outputs (single or multiple output design).
Isolated supply - you can specify to use isolated or non-isolated power supply design.
Output Type - "CV" stands for "constant voltage", and "CC" stands for "constant current". In constant-voltage mode, the voltage across the output terminals is held constant while the current through the output terminals may vary according to load conditions. The output channel behaves like a voltage source when in this mode. For constant-current mode, on the other hand, the supply maintains a constant current over varying output voltage conditions, including that of a short circuit. The output channel behaves like a current source when in this mode. “CV/CC”, or “constant voltage/constant current” mode, is a combination of both modes. It is mostly used for battery chargers and LED drivers. When charging a battery, for example, current is limited to a constant value as the battery voltage rises from a discharged state; once the battery voltage reaches the target, the power supply maintains a constant output voltage, as the charging current decreases until the charging cycle is complete.
Topology - A switching power supply topology is a particular circuit configuration of switching elements, like power transistors and rectifiers, and energy storage components, like inductors, transformers, and capacitors. At the heart of each power supply topology is a switching regulator controller capable of modulating drive control signals based on feedback to insure proper regulation over a range of line and load conditions. Each topology has inherent advantages and disadvantages in size, cost, and performance.
High PF/Low THD - Select “Yes” to designate a product family that is optimized for high power factor (PF) and low total harmonic distortion (THD). For AC circuits, the power factor is the ratio of the real power (kW) used for work to the apparent power (kVA) supplied to the circuit. Total harmonic distortion measures waveform distortion caused by harmonics and is the ratio of the power of all the harmonics to the power in the fundamental frequency.
Filters are also used for Help Me Choose feature.
If you don't know which device family to choose for your Power Supply use Help Me Choose feature. Help Me Choose button becomes active after you use the following filters: Application Type and Total PO.
