Akula0083 30 Watt Self Running Generator.

Maybe verpies or TK try draw schematic how sync two generators.

Connect pins #5 of two TL494s together.

Hi MenofFather,

Thank your share

Connect pins #5 of two TL494s together.

Dear verpies,
Pin #5 is a capacitor (.nF) connected to the common ground, as well as to determine the oscillation frequency of the TL494. To connect two chips with each other, need to create intermediate frequency divider circuit two way out? or other simpler way?

Changing R12 resistor, how I understand, in 30 W lantern we change how many pulses go in pachka. So not need maybe change C3 capasitor.


Relisten... Found place were asking about inductor of 30 W lantern. Asking or normal be 100 microhenries. Akula say, that it be too much. So it have about 80-20 microhenries.


This inductor must be stabileset acording C3 capasitor, something like this.
R11 to pin 1 just ajust voltage (probarly corect to V2).


In that lantern akula say, that duty cycle of pulses be 1.7 megaherc. So here about 600 ns maybe duration of pulse. And frenquency of this pulses seems be 400-460 kiloherc.


Akula say "По моему он на 1,7 зарезонировал, я на нём 1 и семь скважность и подобрал..." So he not shore but in this 30 W lantern resonans of ferite be on 1.7 megaherc.


Load Akula use in 30 W lantern of many LEDs 30 W. Incandesel lamps as load not good. But in begining he start from small load.


How I understand, how much pulses be in pachka is not wery important, from here depends only power, that you give and get. More pulses in pachka - more power give and get, less pulses in pachka, less power put and get.

No, pin #5 is pin #5 - not a capacitor.

No, it is not necessary to create an intermediate frequency divider in order to o connect two chips with each other, but it is necessary if you want to run these two chips at different frequencies.

I think we have a language problem
