Answer #1

4) for both positive and Negative half cycles of A.C Signal if current flow through the road resistance will in same direction then the output will be a D.C.

♡ > Output taking positive Half cycle of A.C. Signal (PNC) for a diode to.ru Diode will be in Forward bias (means current wil• equivalent to here at Pont A VAS VB but VCVA (Flow to curent I direction) (FB) (R.B) (open circuit e at point B V LUB & R.BAt Polat A CUA<vel same reason as - point D R.B) Oren cincauit. As initially VB comes D will be forward & due to flow in Chau

    part g Q4. Most electronic systems need a dc voltage to work properly. The AC-to-DC power supply system is including a transformer, a rectifier and a capacitor input filter. The AC input voltage is 110 Vrms at 60 Hz. (a) Draw the full wave bridge rectifier circuit with transformer which steps down voltage to safer and lower levels that are more suitable for use with diodes (b) Show how the capacitor input filter connects to the rectifier output in the...

    DC-AC inverters have many commercial and residential applications, including uninterruptible power supply (UPS) units, adjustable speed drives (ASD) for AC motors, and electronic frequency changer circuits. They are also used in solar electrical systems where batteries are charged from solar panels and used as the input DC voltage source. The inverter circuit converts the DC into AC voltage of desired frequency. Most of us are also familiar with HVDC transmission systems, where high voltages are first converted from AC to...
