Any analysis from you experts will be helpful.
A small test i have conducted is I get the instant output when i manual switch the transformer by ktv the bulb between collector and emitter. Check also for a bad solder joint on the emitter to R4 connection path.
Choosing IC with EN signal 2. Try to modify R7 down to K, this time using a good transistor the light bulb must be turned on I have even changed the transistor and i don’t see the transistor is open or short.
I have changed the faulty components 8AV and 8v2 Zener and no other components found to be faulty. Before I tried R9 with 10 ohms also Also did you check for any short-circuit in the secondary section? Battery charger using pic using pwm Digital multimeter appears to have measured voltages lower than expected.
The new transistor also doesn’t switch. I have replaced C4 which didn’t help.
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 not be pure DC. Part and Inventory Search. How do you datasheeet an MCU design to market quickly? Losses in inductor of a boost converter 9. Regarding the transdormer being faulty – it’s rare for them to fail but shorted turns in any winding will prevent the circuit oscillating whilst not significantly changing DC conditions.
Heat sinks, Part 31001 Also R10 is good and I am able to glow a 60W bulb from collector and emitter of transistor.

I got only this from the shop when I asked for S. Does this make any 130011 here. If you really have more than 1. What is the function of TR1 in this circuit 3. Dec 248: Also I have tried removing Z2 and Base gets 11v.
Input port and input output port declaration in top module 2. Battery Charger using LM 0. You may try and change the D1 diode, C1 capacitor….
KTC MJE IC 20pcs/lot
I am confused, whether the transistor needs more base voltage Maybe you need a new transistor. CMOS Technology file 1. My concern is whether 8v is enough to switch this transistor and Z1 voltage of 0. First you need to ktv C4.
Few detail for your analysis. I will check reducing R7 value whether it helps My guess is that the 8V at Dagasheet is not a DC voltage but an alternating signal that is confusing your meter.
It’s better to share your questions and answers on Edaboard so we can all benefit from each others experiences. The transistor is not switching even in 8v means, does it needs more voltage. Equating complex number interms of the other 6.
I am sure the problem is in primary side and i don’t see any bad solder joints. Dec 242: I have uploaded a similar circuit. Last edited by jayaramc; 1st July at I am worried why the transistor is not switching although it has a base voltage of 8v.
Collector to Emitter voltage is v. The time now is Turn on power triac – proposed circuit analysis 0. How reliable is it? Distorted Sine output from Transformer 8. With all these actions tried already I am not sure what else remains: AF modulator in Transmitter what is the A?
Synthesized tuning, Part 2: PV charger battery circuit 4. ModelSim – How to force a struct type written in SystemVerilog?
