Making the best use of capacitive current: Comparison

2021/3/31The design of the discharge cell and the ratio between charge and discharge times can be further optimized to make better use of stored charge of the granular capacitive bioanodes. In terms of design of the discharge cell, a better understanding of the discharge process is needed and how it depends on contact resistance and mass transfer processes.

MHD

2017/7/1With the increase of discharge time, the heating process changes from a constant volume heating process to a constant pressure heating process, causing the thermal efficiency decreases. In the capacitive discharge process, the inductance plays a determinant role on the energy deposition speed, and the capacitor coupled with the voltage determines the energy stored in the capacitor.

Capacitor discharge ignition

History Nikola Tesla The history of the capacitor discharge ignition system can be traced back to the 1890s when it is believed that Nikola Tesla was the first to propose such an ignition system.

TransformerLess Low Cost DC Power Supply : Resistive

Simply speaking, in the capacitive circuit, roughly 150mA will flow through R1 and R3 once plug in. In fact, R3, and R2 in resistive circuit are redundant. They are necessary only in transformer power supply to limit the current passing through the zener diode as theorectically the transformer power supply can suppy an infinite amount of current without load.

Dielectric barrier discharge

Dielectric-barrier discharge (DBD) is the electrical discharge between two electrodes separated by an insulating dielectric barrier. Originally called silent (inaudible) discharge and also known as ozone production discharge or partial discharge, it was first reported by Ernst Werner von Siemens in 1857.
