Hybrid-Switched-Capacitor VRM with Zero-Voltage-Switching Intermediate Voltage Rails
The paper presents a novel hybrid-switched-capacitor voltage regulator module (HSC-VRM) design with Zero-voltage-switching (ZVS) intermediate voltage rails for CPU power supply. This approach combines a switched-capacitor stage to split the input voltage into multiple switched voltage rails, along with a multiphase buck stage connected in parallel …
Measuring Capacitors
The known capacitor is referred to as the ''standard'' capacitor and is often a high-accuracy type meant for testing, hence the ''s'' designator. However, the simple capacitance bridge circuits commonly found online and in educational texts suffer from a major problem: They really only work with near-perfect capacitors, which means air-gap, quality mica …
Considerations on bootstrap circuitry for gate drivers
One of the most common methods to generate this extra voltage is a bootstrap circuitry composed by a capacitor and diode series connected to the switching node. This document describes the basic principles of this circuitry and provide guidelines on the proper selection of the components.
Capacitor Filter Working Principle
A half-wave rectifier with a capacitor-input filter is shown in Below Figure. The filter is simply a capacitor connected from the rectifier output to ground. RL represents the equivalent resistance of a load. We will use the half-wave rectifier to illustrate the basic principle and then expand the concept to full-wave rectification. During the positive first …
