常见问题

What is the purpose of a rectifier and filter circuit in a plasma power supply?

It converts AC power to stable DC power required for generating and maintaining plasma arcs in industrial processes.

How does the filter reduce ripple in the output?

Capacitors store charge to smooth voltage, while inductors resist current changes, together minimizing AC fluctuations in the DC output.
