A phase controlled single phase rectifier, supplied by an AC source, feeds power to an
R-L-E load as shown in the figure. The rectifier output voltage has an average value given
by $${V_0} = {{{V_m}} \over {2\pi }}\left( {3 + \cos \alpha } \right)$$, where $${V_m} = 80\pi $$ volts and $$\alpha $$ is the firing angle. If the power
delivered to the lossless battery is 1600 W, $$\alpha $$ in degree is________ (up to 2 decimal
places).
