TL494 DC TO DC STEP UP 12V TO 40-90VDC CT

TL494 DC TO DC STEP UP 12V TO 40-90VDC CT

Hello friends, on this occasion I will share a complete schematic and PCB layout with BOM files and CPL files for the DC to DC 12VDC to 40-90VDC Converter kit which can adjust to the twisted step-up transformer. Here is a DC to DC Converter scheme using IC TL494 with 8 mosfet IRB4110.

For the transformer, you can use the ferrite EE55 transformer which is rolled using an email hook.
For the primer, use a wire with a diameter of 0.8mm, as much as 7 copies, wound 3 + 3 times.
And the secondary uses 3-fold 0.8mm wire wrapped around 22 times for the CT 90VDC voltage.

To make it easier, elcircuit.com provides its PCB Layout which you can download at the end of the post.

  4. Non Standard Work and has many errors: You have marked 12V+ for VCC and -12V for GND. This means you have a 24V DC supply. Also how can the output of TL494 drive 3 mosfets without any Buffer transistors?????
