A single-phase half-controlled bridge converter supplies an inductive load with ripple free load current. The triggering angle of the converter is . The ratio of the rms value of the fundamental component of the input current to the rms value of the total input current of the bridge is ________ (rounded off to 3 decimal places).

A single-phase full-controlled thyristor converter bridge is used for regenerative braking of a separately excited DC motor with the following specifications:

Assume that the motor is running at 600rpm and the armature terminals of the motor are suitably reversed for regenerative braking. If the armature current of the motor is to be maintained at the rated value, the triggering angle of the converter bridge in degrees should be ________ (rounded off to 2 decimal places).
