4 FAQs about [High voltage energy storage external switch]
How does a high power switch work?
In contrast to AC switching, where zero-crossing of voltage and current facilitates quenching and in some cases prevents arcing, only the high-power switch can extinguish the arc generated by a DC source.
What is a solid-state switch?
The solid-state switch program is divided in two basic categories: Switches with a fixed on-time (product groups A to B4) and switches with a variable on-time (product groups C1 to C8). Switches with fixed on-time are very cost-efficient and are used mainly in simple charge or discharge circuits.
What is a Behlke switching module?
BEHLKE switching modules are always galvanically isolated. They can be used as high-side switches for positive as well as for negative voltages. If the voltage polarity must change during operation (e.g. in TOF masspectrometers with positive and negative ion accleration), then the AC switch technology comes into consideration.
What is a DC switch?
2. Basics of DC switching Whenever an electrical high-power device is turned off und load (for example, motors, transformers, energy storage or similar power loads), its switch, relay or contactor transitions from a closed to an open state under load and an electrical arc (break arc) occurs between the two contact points (electrodes) of the switch.
