The Circuit is based on a Toroid transformer which converts 230VAC to 15VDC (this value is the effective value, The peak-to-peak voltage is roughly 42Vpp). The four diodes D1, D2, D3 and D4 form a bridge rectifier – a circuit used to convert AC voltage to DC voltage. With this we can convert positive and negative halfwaves of the two sine voltages of the transformer's secondary windings to DC (roughly 20VDC).
