2N6277 Datasheet, Equivalent, Cross Reference Search

Hello I love this circuit I built another circuit and the output decreases with load datasjeet according to ur inverter this should not happen. Hi for pure sine wave generation a function generator chip with driver and output transformers with MOSFETs or transistors to be used, with AGC and other feed backs to dataaheet used for stability.

Hi Simeon, thank you! R11 limits limits the current through the indicator LED D2. Please send 2n677 circuit. Hi Sim this inverter is more effficient as per load requirement the output is pumped. When I checked the current at primary, it consumes around 8Amps. Not even for 24 minutes how could be for 24hrs???!!! If we are going to get that complicated,at least make it better. If possible please send me as early as possible. If u need the modification of the watts to watts with mosfet and also a powerful charger for it contact me on or email simeonm gmail.


If u need the circuit and a transformerless 3-stage automatic charger 12v 15amps. Reply to Ed There is no problem with the circuit diagram.

Hence I am not 2h6277 if they are switching alternatively. I want to commend you on this good job, please keep it up however I have these following observations and questions: Pleae sir, can I convrt the Watt inverter to Watt or more by just inceasing number of driver transistors or mosfets and the suitable transformer T2 without alter the oscilator and the feedback circuits, thanks.

Because the output at pin 14 and 11 reads 3.

At oscilator side dagasheet are GND at 2N emitter which line can this be connected. From where i can get transistor 2N in india? Sir i need to build a PWM inverter with output voltage control 50vv. If I want to add more transistors to archieve for example W, which transistors would be added and doe it require more base resistors too?

NTE – NPN Transistor, SI Power Amp/Switch

Preset R9 can be used for adjusting the inverters output voltage as it directly controls the amount of voltage fed back from the inverter output to the error amplifier section. Thanks alot more grace to your effort.


It is hard to find, use 2 x 2N instead or 3 x 2N Yes you can use more transistors in parallel to achieve higher power output. I find this type of circuit and now got it thanks for post this circuit.

These are the signals which drive the subsequent transistor stages. Hi is this a modyfied output inverter. Hi Eniola it is a Motorola power transistor there is no equivallent. C10 and C11 are meant for bypassing noise from the inverter output.

Hi Sim except where you require only pure sine wave. T1 is not shown in the diagram. It will not be constant in cd circuit. Pin 14 and pin 11 are the emitter terminals of the internal driver transistor of the IC.

This circuit doesnt contain battery low shut down. If it is possible to send me a procedure of testin of transistor and other semi conductors in a circuit or out of circuit by testing meters. You could get a square wave with less parts to fail and wind your own M.
