a-.. iii | :.le! lor ! 1 No Spac Heading 1 Heading 2 Title ', Styles Paragraph True or False: In practical applications, the half wave rectifier is preferred over the full-wave rectifier because the average current supplied by the source is not zero in the half-wave rectifier. (Select the one best answer from the choices given below.) C a This is true, in general. C b This is true, only for high power applications. C This is false, in general. Thls won couly or ow paer spiais A single-phase half-wave rectifier with a capacitor filter has a 120-V ms 60-Hz ac source. The capacitor value has been selected to provide for a nearly constant de output voltage (approximately equal to the rectified peak voltage). The load (resistor) absorbs 100 W. Determine the approximate peak inverse voltage (PIV) across the diode. (Select the one best answer from the choices given below). a 0.7 V b 57v 170 V 240 V 8-340 v

Explanation / Answer

First Statement is false because For most power applications, The harmonic content of the half wave rectifier's output waveform is very large and consequently difficult to filter. ..option C is correct

PIV of the half wave rectifier is Vm = Vrms * sqrt (2) = 170 is correct option
