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 Vo= Vm/2π (3 + cos α), where Vm = 80π volts and α is the firing angle. If the power delivered to the lossless battery is 1600 W, α in degree is ________ (up to 2 decimal places).
