Fully-controlled single-phase bridge converters are two-quadrant converters having unidirectional current with positive and negative voltage polarity. Therefore, they can function as a controlled rectifier or inverter. But for some applications that do not use Inverter mode operation, a fully controlled four-thyristor converter and its associated gate control and control circuitry make the system unnecessarily complicated.
Three-phase half-bridge bridge converters and fully-controlled bridge converters are widely used in industrial applications up to approximately 15kW of output power. Three-phase controlled rectifiers provide
vdc (max) = 2vm / Π
The output ripple frequency is equal to twice the AC power frequency. Single-phase full-wave controlled rectifiers provide two output pulses during each input supply cycle and are therefore referred to as two pulse converters.
