DC DC Converter Circuit is based on sg3525 smps control IC, it can provide 900w power. The power transformer used is etd59 output 4n25, isolated with opto coupler, it gives a symmetrical + – 70 volts total 140 volts output with 12 volts. There is a pcb file prepared with ares that can be used as an auto amplifier supply.
symmetric 70v complete DC DC Converter
CAUTION Be careful is working with high voltage capacitor circuit connections Beware + – If you connect the high voltage polarity may be large explosions before running the insured Power Line circuit, protective goggles

Hi .
Thank you very much for your reply.
In the pcb, the secondary connections of the 4 cores are connected to Shadaki diodes.
But your explanation is about how to wind the core of the three connections Ac1, GND, AC2, please guide me.
Hi,
see diagram;
Hello, thank you very much for your kindness
Please give me the bobbin filter coil including core diameter, wire thickness and number of coils.
And what is the function of the romate++ part in the circuit and what voltage is it connected to? Is it disconnected from the battery input voltage or…?
I am very happy to have found a good friend like you.
Hi . What is your suggestion for printing multi-layer pcb board? 3 layers or single layer?
Hi,
Filter coil removed from faulty atx power supply. 5v line of the coil is used. 10 turns of 2x 1.5mm wire
PCB drawing is single layer. REMOTE connected to the 12v line. Used for standby mode
Hi
The coil filter that I wanted is for the 12v to +70v 0 -70v DC to DC inverter circuit. I think you said another circuit because there is a different board picture.
Please upload the coil filter of this circuit. How many turns of wire? Wire thickness? The diameter of the nucleus of Troid?
Thank you
I’m talking about the 12V input filter coil.
Toroid is not used in this circuit. ETD59 core used
Hi
In your circuit, an ETD59 transformer is used for voltage conversion and a bobbin filter, and you have already loaded the winding of the transformer, and now I wanted the coil of the bobbin filter that is installed above the 100 MF capacitor of the IC Generator SG3525.
Thank you
10 turns of 2x 1.5mm wire
hi
Please ask me the inductance data and the test conditions of the etd59 transformer without the inverter circuit
thank you
Hello .
A workshop wants to wire the transformer for me and needs this information from me for testing
I have a problem with the transformer, please help?
Please ask me the inductance data and the test conditions of the etd59 transformer without the inverter circuit
thank you
Hi
Only PCB layout files. Where is Schematic. Please share
