Sepic and Cuk power converters working as power factor preregulators (PFP) in the discontinuous conduction mode (DCM) present the following desirable characteristics for a PFP: (1) the power converter ...
Active Power Factor Correction (PFC) Circuit With Resistor-Free Zero-Current Detection - IEEE Xplore
An active power-factor correction (PFC) circuit is presented that employs a newly proposed resistor-free zero-current detection (ZCD). While the conventional ZCD requires either a sensing resistor or ...
It can also automatically identify the resistor or capacitor value using 3 scales for better approximation. The Garagino microcontroller was used, but it is fully compatible with the Arduino ...
Apple has determined that a very small percentage of Mac mini (2023) devices with the M2 chip may no longer power on. Affected devices were manufactured between June 16, 2024 to November 23, 2024. If ...
We propose a new computational scheme for calculating the phonon band diagrams of molecular crystals. In conventional computational models, the vibrational unit is typically an atom, which leads to ...
