6 FAQs about [The high voltage switch energy storage device is smoking]
What is a high-voltage solid-state switch?
Finally, a high-voltage solid-state switch is developed based on the SiC MOSFET series connections, whose output pulse width is adjustable from 20 to 300 μs, frequency is adjustable from 1 Hz to 3 kHz, the maximum output voltage can reach 57 kV (1 Hz), and the overcurrent protection time is about 1 μs. Circuit design.
What is a DC switch?
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.
How to improve the voltage level of a single switch?
By optimizing the chip structure, the voltage level of a single switch can be improved. Due to the immaturity of the production process and the positive correlation between the blocking voltage and the on-resistance of the switch, it is difficult to improve the blocking voltage and the continuous forward current of a single switch simultaneously.
Does a high power switch prevent arcing?
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.
