Question 1   Consider the adjacent circuit diagram of three different rectifier topologies connected to an 373 Volt three-phase AC system. Assume a load resistance of 36Ω in ALL instances with NO losses in the rest of the circuit. Observe the connections to the AC supply and determine the parameters for,    Rectifier B: 1.1) the maximum voltage across the load and the dc load voltage and the r.m.s. load voltage. 1.2) the rectification efficiency and the r.m.s. current rating of the diodes. 1.3) the conduction period of a single diode and the PIV rating of the diodes.
