Answer: b Explanation: Vo = Vs/1-α.
Answer: b
Explanation: Vo = Vs/1-α.
Answer: c Explanation: During Ton, the energy stored in the inductor is Win = Vs x Ton x (I1+I2)/2 During Toff, the energy released by the inductor is Wout = (Vo – Vs) x Toff x (I1+I2)/2 Considering ideal condition, Win = Wout Vo = Vs x (T/Toff) α = Ton/T Vo = T/T-Ton = Vs/1-α.
Answer: c
Explanation: During Ton, the energy stored in the inductor is
Win = Vs x Ton x (I1+I2)/2
During Toff, the energy released by the inductor is
Wout = (Vo – Vs) x Toff x (I1+I2)/2
Considering ideal condition,
Win = Wout
Vo = Vs x (T/Toff)
α = Ton/T
Vo = T/T-Ton = Vs/1-α.
Answer: c Explanation: When the switch is off, the inductor is has stored energy from the earlier chopper on operation. The current starts to flow from Vs-L-D-Load-Vs, hence current is decaying as the inductor is discharging and the load voltage is Vs + Vl (inductor voltage) Vl = L(di/dt) Vo = Vs +Read more
Answer: c
Explanation: When the switch is off, the inductor is has stored energy from the earlier
chopper on operation. The current starts to flow from Vs-L-D-Load-Vs, hence current is
decaying as the inductor is discharging and the load voltage is Vs + Vl (inductor voltage)
Vl = L(di/dt)
Vo = Vs + L(di/dt).
Answer: b Explanation: It has two terminals anode and cathode same as that of a ordinary diode. In fact, a power diode is nothing but a signal diode with a extra layer.
