This 7-part series discusses tips and best practices for selecting the appropriate components for your switching power supply.
Learn about the advantages and disadvantages of classic boost PFC, dual boost bridge-less PFC, totem-pole bridge-less PFC and interleaved boost PFC. Also learn about the main power loss components in typical PFC circuits resulting in bridge low, choke loss, boost diode loss and switch loss.
Learn about the design methodology and test results from the 230 V, 3.5 kW power factor correction (PFC) reference design.
Learn the difference between different PFC classifications and the advantages and disadvantages of peak current mode control, average current mode control and hysteresis current mode control.
Learn what power factor correction (PFC) is, the basics of power factor measurement and why PFC is needed. Also learn about EN6100-3-2 and Energy Star standards for power supplies.
Applications Engineer Jason Tao discusses PFC basics, topology comparisons and design considerations to achieve a cost-optimized and efficient PFC design.
The Phase Shifted Full Bridge (PSFB) has always been considered the best design for high power DC/DC conversion. However, a newer technology called Full Bridge LLC (FB-LLC) has recently been used and accepted for high power DC/DC conversion. In this 3 part series, we will go in-depth in discussing the pros and cons of both the PSFB and FB-LLC. We will then compare the basic problems between the PSFB and FB-LLC and give ideas on how to choose between the two given a certain application. Lastly, we will review some Reference Designs.
The training provides a very comprehensive introduction of the commonly-used interface including RS-485, RS-422, ProfiBus, RS-232, IO-Link, CAN and LIN. These interfaces are used in the application of Factory Automation and some other industrial application. For the engineer who needs to deal with interface system design, this is a very useful training.
EMI (electromagnetic interference) mitigation is a critical step in the design process in most electronic systems, and especially so in the automotive world. In many cases, automotive OEM emissions requirements are even more stringent than both national and international standards bodies like the FCC. Unfortunately, by their nature, switching regulators are sources of EMI; but, in order to keep power supply designs small and efficient, switchers are a critical component. So how can you reap the benefits of a switching regulator while still meeting challenging EMI requirements?
This sections covers tips for selecting the appropriate inductors for your switching power supply.
We are all well aware that the demand for Electric Vehicles (EV) is increasing rapidly. This eight-part training session begins with a description of a typical EV system in part 1. Part 2 is a brief description of how both Lead Acid and Lithium Ion batteries are charged. Part 3 focuses on the types of power factor and harmonic currents. Part 4 discusses power factor correction and the typical boost PFC stage.
