A 1N4738A zener diode has a ZZ of 4.5 Ω. Taking the data from the datasheet we have VZ = 8.2 V with a test current, IZ, of 31 mA. What is the voltage across the zener terminals when the current is 15 mA? When the current is 55 mA? Make the representation of the values ​​by means of their curve characteristic.

A voltage regulator is a device that: Maintains a fixed DC voltage. O Maintains a fixed AC voltage. O Maintains a fixed DC current. O Maintains a fixed AC current.

8.* A single phase bridge rectifier supplies a IkW washing machine induction motor drive. The smoothing capacitance is 6.8 mF and the smoothing inductance is 5 mH. At full load, the equivalent resistance of the induction motor is 24 2. The ac supply is 220 V (60Hz). (a) (b) (c) Estimate the ripple What is the capacitor 'de link' voltage under full load? What is the % voltage regulation no load to full load? ?

Please solve 9.6

(c) A 50 Hz sinusoidal AC voltage source of peak value V, = 340 V delivers power to a resistive load of 50 n. (1) Calculate the average power delivered. (i) The AC source is now connected to the load via a full wave diode bridge. The turn-on voltage of the diodes is 0.3 V. Calculate the peak voltage across the load and the average voltage across the load. (ii) Explain how a smoothing capacitor can be used to hold up the voltage across the load. Compare the efficiency of the rectifier with and without the smoothing capacitor. (iv) Define "regulation" as applied to the output voltage of a rectifier and explain why an LR filtered rectifier bridge provides better regulation of the load voltage than an RC filtered rectifier bridge.

The 3-phase half-wave diode rectifier feeds a load consisting of a 50-ohm resistor. The sinusoidal sources in the input of the rectifier are wye-connected and phase-to-phase rms voltage is 380 volts.
