If you wish to use a double symmetrical power supply circuit but don’t have a center trapped transformer you can use an electronic circuit in the following configuration. This double symmetrical power supply circuit uses a second rectifier bridge coupled with secondary coil of the transformer using two capacitors (C1 and C2). Because the DC voltage produced is not in galvanic contact with the terminals of the transformer, where is connected the other one bridge rectifier, both voltages can be combined into a symmetric voltage.
Operating voltage of capacitors must be at least equal to the peak voltage of the transformer.
