In comparing the operation of the half-controlled 2-pulse circuit with that of the fully-controlled circuit, which of the following statements are evident? 1. Since half the thyristors are replaced by diodes, a half-controlled converter costs less than a fully-controlled converter. 2. Due to the freewheeling action with a half-controlled bridge-circuit power factor is improved in half-controlled converters. 3. The AC supply current is more distorted due to its zero periods with the half-controlled circuit, compared to a fully-controlled bridge circuit. Select the correct answer using the code given below :
