Voltage regulators

Voltage regulators

As regards their power supplies, controllers and computer can be quite sensitive to fluctuations in the mains voltage. And power from the socket is not so uniform. The perfect problem-solvers when fluctuations in the mains voltage occur are voltage regulators. In the power supply unit they are placed downstream from the rectifier, and stabilise the fluctuations in the incoming voltage. In this way a linear power supply can be created with only a few components. This replaces for instance cheap plug-in power supply units which often tend to lead to faults.
