PFC Circuit Design and Layout for Power Systems

PFC Circuit Design and Layout for Power Systems Much as we would like, the power input into a PCB is not always a clean DC or sinusoidal signal. DC coming from a rectifier will have some ripple from the output capacitor, and AC signals can contain noise or be less-than-perfect sine waves. There are some ways to correct these problems, either by choosing the right filtration circuit or by shaping the input wave to produce maximum power output to a load in the system. If you’re working with an Read Article

Modeling Capacitor Impedance Vs. Frequency Using an Excel Spreadsheet

Modeling Capacitor Impedance Vs. Frequency Using an Excel Spreadsheet As noted in an earlier article, based on class notes from our two-day design course, getting the power subsystem design correct is the most challenging aspect of today’s high-speed PCB design process. A major aspect of this process is modeling the power supply to ensure that it will function properly in the end product. A critical part of this modeling effort focuses on being able to model capacitor impedance vs frequency. This is simple enough Read Article

Low Noise, Low EMI Power Distribution

Low Noise, Low EMI Power Distribution This board has several loads on it, but it is purely a distribution board with no regulation. The main loads are the hefty 5V Tilta nano focus motor, 5V SDI to HDMI converter, 5V Tilta follows focus control, and the battery voltage powered monitor. Out of these, only the SDI to HDMI convert needs remotely clean power. The motor, however, is very electrically noisy, so it needs good isolation. Read Article

PDN Impedance Measurement For Power Subsystem Design

PDN Impedance Measurement For Power Subsystem Design In order for a power subsystem to provide adequate power, a PDN impedance measurement versus frequency must be performed with custom test probes. Read Article

Know the Power Dissipation

How to Calculate Power Dissipation Understanding the power dissipation of an individual component, an electrical block, or even the whole electronics system is essential for electronics engineers. It is important not only to avoid exceeding the maximum limits of components but also to calculate unknown parameters in input or output sides because power dissipation is related to system voltage and current. In this article, I describe my practices for analyzing power dissipation in Read Article

12V DC Uninterruptible Power Supply

12V DC Uninterruptible Power Supply I live in a rural village that tends to have intermittent power when there are high winds or storms. Because of this, my computers, servers, and network equipment are all on relatively low-cost, uninterruptible power supplies. These all run on sealed lead acid batteries and are not an overly efficient way to power a DC device such as a Raspberry Pi or internet router as the incoming mains. AC charges a DC battery, which then creates AC power Read Article

High Voltage SMPS PCB Layout to Minimize Heat and Noise

High Voltage SMPS PCB Layout to Minimize Heat and Noise Whether you are performing AC-DC conversion or DC-DC conversion, switching power supply layouts are common in high voltage design and must be constructed carefully. Although this system is quite common, it will easily radiate EMI due to the fast changes in voltage and current during switching. Designers can rarely adapt existing designs into new systems as a minor change in one area can create an EMI problem that is difficult to diagnose. With Read Article
