A full-bridge DC-DC converter is fed from DC link voltage of Vdc = 48V as shown in figure. The ratio of transformer winding turns Ns/Np = 6 and converter operates at a switching frequency of 50kHz with duty ratio of 0.5. The peak inverse voltage of the secondary side diode is Answer V.

n a bridge type full wave rectifier with center tapped , if Vm is the peak voltage across the secondary of the transformer, the maximum voltage coming across each reverse biased diode is a.  *Vm2 VmVm/2√(Vm)

A half wave rectifier has a 200 V rms. source and the step-down transformer has a turns ratioof41.What will be the peak voltage across the load ignoring thedrop acioss the diode?

A half wave rectifier has a 200 V rms. source and the step-down transformer has a turns ratio of 4 ∶ 1. What will be the peak voltage across the load ignoring the drop across the diode?

Half Bridge and Full Bridge Inverters,

A half wave controlled rectifier is used in certain application is connected to an AC Voltage : v(t) = 300sin(314.159t). The RMS value of the output voltage from such a converter at a resistive load of 3kW at a Firing angle of 60 degrees is....Select one:a. 134.54b. 269 Vc. 189.99d. 72.56 V
