MJE Datasheet –

It’s better to share your questions and answers on Edaboard so we can all benefit from each others experiences. I have changed the faulty components 8AV and 8v2 Zener and no other components found to be faulty. I have replaced C4 which didn’t help. I am confused, datasheeg the transistor needs more base voltage PV charger battery circuit 4.

A DVM will not tell you the truth when measuring in the presence of an AC component and this circuit is a single transistor oscillator so the signal will datashfet be pure DC.

Kindly help me to get this circuit working. What is the function of TR1 in this circuit 3.

I get 8v at base. I will check reducing R7 value whether it helps Input port and input output port declaration in top module 2. Now I have tried removing Z2 and Base gets 11v. I can see the max voltage is 9v ktx this transistor.


The transistor is not switching even in 8v means, does it needs more voltage. How reliable is it? CMOS Technology file 1. Choosing IC with EN signal 2. Try to modify R7 down to K, this time using datashset good transistor the light bulb must be turned on Distorted Sine output from Transformer 8.

Also is it normal that the voltage across the signalling diode Z1 as 0. Before I tried R9 with 10 ohms also Dec 248: Also did you check for any short-circuit in the secondary section? You may try and change the D1 diode, C1 capacitor…. How can the power consumption for computing be reduced for energy harvesting?

Base to Emitter voltage is 8. Also I have tried removing Z2 and Base gets 11v. A small test i have conducted is I get the instant output when i manual switch the transformer by keeping the bulb between collector and emitter. The time now is Few detail for your analysis. Regarding the transdormer being faulty – it’s rare for them xatasheet fail but shorted turns in any winding will prevent the circuit oscillating whilst not significantly changing DC conditions.

Collector to Emitter voltage is v.

Synthesized tuning, Part 2: Dec 242: The new transistor also doesn’t switch. My concern is whether 8v is enough to switch this transistor and Z1 voltage of 0. Equating complex number interms of the other 6. Hierarchical block is unconnected 3. The voltage at C4 is 0. 13001 charger using pic using pwm There is no feedback voltage and secondary output.


AF modulator in Transmitter what is the A?

Part and Inventory Search. Measuring air gap of a magnetic core for home-wound inductors and flyback transformer 7.

Maybe you need a new transistor. Check also for a bad solder joint on the emitter to R4 connection path. My guess is that the 8V at B-E is not a DC voltage but an alternating signal that is confusing your meter. I got only this from the shop when I asked for S. I have uploaded a similar circuit. I have even changed the transistor and i don’t see the transistor is open or short. Digital multimeter appears to have measured voltages lower than expected. Any analysis from you experts will be helpful.

Does this make any difference here.
