Power Supplies Transformers & Rectifiers single silicon rectifier diode may be used to obtain a DC voltage from the AC input as shown in Fig 1.1.2. This system is cheap but is only suitable for fairly non-demanding uses. The DC voltage produced by the single diode is less than with the other systems, limiting the efficiency of the power supply, and the amount of AC ripple left on the DC supply is generally greater.
