Anatomy of Latitude Part Two: "Thread with a Needle” in the context of energy

Anatomy of Latitude Part Two: "Thread with a Needle” in the context of energy We continue to explore the magic of energy conversion in a PWM transducer. Why is it magic? Theoretically, as we saw in the previous section, the line stabilizer initially converts some of the useful power into heat, which makes the efficiency of the line stabilizer less than 100%, and it is expected for technical systems. Theoretically, in a PWM transducer this happens without losses, isn't that magic? A PWM transducer, like a tailor with Read Article

The Best Capacitor Circuit Simulator for PCB Design

The Best Capacitor Circuit Simulator for PCB Design A capacitor is a fundamental element in integrated circuits and in PCB design, and it’s hard to think of a circuit that doesn’t contain at least one capacitor. A capacitor’s behavior and interaction with other components in a circuit generally needs to be simulated to ensure the design will operate as intended. Capacitors can provide filtering, blocking, and power stability behavior depending on their use in a circuit, and a capacitor circuit Read Article

The Best Power Supply Circuit Design Tools With Simulation

The Best Power Supply Circuit Design Tools With Simulation From bench-top power supplies to power regulator circuits on embedded boards, designers often need to create a custom power supply circuit design and layout. These circuits sound simple to design, but it takes the SPICE-based simulation and verification tools in Altium Designer to create a stable, high-quality power supply circuit design. Altium Designer gives you much more than circuit design and circuit simulation tools; you can easily create Read Article

S-parameter measurement

S-Parameter Measurements and Errors in Power Integrity No matter where you look, it seems S-parameters never go away! They are mandatory tools for understanding some systems, such as an interconnect or antenna, while other network parameters can sometimes give a better conceptual understanding of electrical behavior. These parameters are normally reserved for signal integrity among electronics engineers, but if you look hard enough, you’ll find that S-parameters are also used for power integrity Read Article
