Difference Between AC and DC Coupling in the Conditioning & Refrigeration Industry
AC coupling lets only changing signals through, blocking steady ones. It's like focusing on waves in the ocean but ignoring the overall water level. DC coupling lets both steady and changing signals through. It's like looking at the ocean waves and the overall water level. In case you have been wondering what difference AC and DC Coupling make to your Air Conditioning or Refrigeration, this blog might just give you the answers to your questions. 3 Key Differences Between AC and DC Coupling Working Principle So what is a coupling? A coupling is a mechanical device connecting two parts or objects like shafts. The first point of difference is the concept behind their functioning. In AC coupling there exists a Capacitor that blocks the incoming DC signal, i.e. AC coupling only accepts the AC signal and removes the DC offset, whereas in DC coupling the capacitor is absent which allows both DC and AC signals to pass.
