AN2495 Application note 3-phase 80 W SMPS with very wide-range input voltage based on the L6565 and ESBT® STC04IE170HV 1 Introduction The purpose of this application note is to explain the design of an 80 W 3-phase auxiliary power supply for motor drives and welding applicatio...
like TV, Printer, Music Player etc. consists of a power supply unit built into it which converts the AC mains voltage to a suitable level of DC voltage for them to operate. The most commonly used of type of power supply circuit is theSMPS (Switching...
The schematic in figure 17b shows also how the function is included in the control loop. With a proper selection of the external divider R1-R2 it is possible to achieve the optimum compensation described by the lower curve in the diagram of figure 16. In applications where this function is ...
Schematic Diagram: FAQ: 1. Are you factory? Yes, we have more than 17 years production experience. 2. All goods are tested before shipment? Yes of course, all goods are tested with different testing machines for different electrical parameter. ...
Figure 1: Functional diagram of a flyback converter using a single MOSFET switch and a flyback transformer. (Image source: DigiKey) The chief advantage of the flyback topology is its simplicity. At any given power level it has the lowest component count of the SMPS topologies. The supply ca...
For the feedback circuitry in your TOPSwitch-GX power supply, I would suggest using PI Expert to do a quick auto-design using a 265-300Vac input with the outputs you've specified. You won't be interested in how it sets up the transformer or primary side circuitry but it will give you...
