It keeps the amplified voltage, when the compressor cycles off, from going back into the wire, which could overload any electrical component in that circuit. In most – if not all – designs, a diode is placed in the wires that go to the AC clutch at the connector. This will step up the voltage as an ignition coil would. In this instance, when the AC is signaled to cycle off, the ground is opened to the clutch and an inherent collapsing of the magnetic field occurs. Like any electromagnet, it is a coil (similar to the ignition coil on a gasoline engine). Going down the field or the road, you may not be aware of this duty-cycle since the interior duct discharge temperature stays almost constant. Because of the way an AC system works, the engagement of the compressor is cycled based on thermal load and the system’s operating pressures. The AC clutch is the same basic design as an electric PTO clutch. One common application is in the wiring to the electromechanical clutch employed to engage the air conditioner (AC) compressor on most engines. Once you recognize the importance of a diode, you’ll be surprised how many are in use in areas you hadn’t thought of. Markets Analysis Back to Markets Analysis.
