What is a DIAC? A DIAC, or Diode for Alternating Current, is a two-terminal, Bidirectional Switching device that conducts current only after its breakover voltage has been reached momentarily. Once this threshold is reached, the DIAC continues to conduct until the current falls below the holding current. DIACs are widely […]

What is a DC Chopper? A DC chopper is a power electronic device that converts fixed DC input voltage to a variable DC output voltage. It is essentially a high-speed switch that rapidly connects and disconnects the load from the power source, effectively “chopping” the DC voltage into discrete pulses. […]
