WebTranscribed Image Text: design a shunt Zener diode regulator that the load current changes from 1mA to 10mA and the supply is 10V ≤ VS ≤ 11V. Use the Zener diode which has VZ=6.8V and rZ=1002 at IZ=20mA with IZK=0.2mA.+ + N 1. Find the optimal regulator resistor R 2. Find the line regulation for 1) 3. Find the load regulation for 1) of R D ... WebSome shunt regulators can become unstable when only lightly loaded. In this case it may be necessary to preload the output with a resistor in order to maintain this minimum load requirement. Doing this modifies R LOAD(min) and it is this modified R LOAD(min) that should be used in the procedure when calculating R3 and C2. Simplified circuit
Shunt generator - Wikipedia
WebNov 1, 2007 · The basic operation of a shunt regulator is described below using a simplified circuit. When the output voltage drops due to a variation of the load, the voltage applied to resistors R 1 and R 2 drops. This then lowers the voltage of V 1, which is the output voltage divided by R 1 and R 2. A shunt generator is a type of electric generator in which field winding and armature winding are connected in parallel, and in which the armature supplies both the load current and the field current for the excitation (generator is therefore self excited). phone charger socket types
Shunt Load – The Project Definition
WebAug 1, 2024 · With this technique, a known resistor R shunt is placed in series with the load and the voltage developed across the resistor is measured to determine the load current. This is illustrated in Figure 1. Figure 1 . Current sense resistors, also called shunt resistors or simply shunts, usually have values in the range of milliohms. WebThe image shows a simple shunt voltage regulator that operates by way of the Zener diode's action of maintaining a constant voltage across itself when the current through it is sufficient to take it into the Zener breakdown region. The resistor R 1 supplies the Zener current as well as the load current I R2 (R 2 is the load). R 1 can be calculated as = +, … WebRearranging the equation, we can find the external load capacitor value: CX1 = 2 (CL - Cstray) For example, if the crystal load capacitance is 15pF, and assuming Cstray=2pF, then: CX1 = CX2 = 2 (15pF - 2pF) = 26pF. It is difficult to know exactly what the stray capacitance is, but if you find the oscillation frequency is too high, the load ... phone charger that lights up
