What is meant by Controlled Rectifier Converting fixed DC Voltage in to fixed AC Converting Variable AC Voltage into Variable AC Converting fixed AC Voltage into Variable DC Converting fixed AC Voltage in to fixed DC

A half-wave rectifier with a reservoir capacitor is connected to an AC mains supply(220Vrms, 50Hz) via a 20:1 transformer. What value of the capacitor is needed forthe ripple voltage of X% of the peak input voltage? The load takes a maximum currentof ???? mA. X= 12% mA = 160
