Three Phase Voltage Tripling Rectifier Circuit

This circuit provides a rectified output voltage which is three times the magnitude of the input voltage. Each phase of the input voltage is connected through a circuit, which circuits are connected in parallel across output terminals.

The input voltage source is connected to the circuit via a wye connected secondary transformer winding 30. The center point of winding 30 is connected to the mid-point of first and second series connected output capacitors 32 and
34. The other side of each of these capacitors is connected to first or second output terminals 36 and 38. The end of each leg 30A, 30B and 30C is connected to terminal 38 through a separate reverse biased diode 40, 48 or 56. The end of each leg of these winding are also connected through a separate capacitor 42, 50 and 58 to the mid-point of separate pairs of diodes 44 and 46, 52 and 54, 60 and 62, each diode pair being series connected. Diodes 46, 54 and 62 are connected in reverse bias to the mid-point of capacitors 32 and 34, and diodes 44, 52 and 60 are connected in forward bias to terminal 36.
