P-resonant control for the neutral point of three phase inverter [PDF]

open access: yes, 2014
In this project, a Proportional resonant (PR) current controller is proposed to maintain a balanced neutral point for a three-phase four wire inverter, which can be used in microgrid applications. The neutral-point circuit consists of a conventional

Microwave digestion for microbes v1

open access: yes, 2022
Before conducting inductively coupled plasma mass spectrometry (ICP-MS), all samples containing organic compounds need to be digested in order to eliminate all organic parts. Microwave digestion is a commonly used method for organism digestion. This protocol describes how to conduct microwave digestion on microbes.
