DC to DC converter circuit size and quite a lot of small passive components used PWM control TL494 SMD type Matchbox output coil in comparison with the size of the image of the PC power supply-12v -5 volts output the same as in the core of filter coil (the coil can not be found alternatives…
TL494 PWM control integrated with the high-voltage applications drive on the floor STW20NB50 MOSFETs used transformer windings information oscilloscope measurements details given me and most of us practice a project that known output transformer is very expensive but the MOSFETs and driver section quite strong other SMPS applications can be useful or less can give…
There are motor driver circuits made with TL494 pwm control IC, different circuits powered by low current P channel N channel and N-P channel mosfets without using mosfet. There are schematic drawings prepared with splan and pcb prepared with sprint layout (for n-p two-mosfet circuit). It is recommended to set up the circuits as shown…
Inverter Circuit is based on TL494 pwm control IC. In addition, the inverter circuit is a good source for different projects, including the core and transformer winding information used in the L6574 ballast driver IC. 12V Fluorescent Lamp Inverter A standard 36/40W inverter circuit for powering Fluorescent Lamps from 12V DC. Ideal for camping, fault…
I have made various modifications on computer power supplies, I shared most of them, and some of them were left unfinished. There are so many options to try, especially by changing the transformer (ei33) windings used, the voltage limit can be exceeded as in this application, an old p3 atx power supply was modified and…
DC DC Converter Circuit Based on TL494 PWM control IC, it reduces the 24v dc input to 12 volts. It has 10 amperes of power. There is a protection circuit with thyristor (BT151) against voltage spikes at the output (crow bar). can be adjusted, but it is generally used as a 24-12 volt converter. You…
Good NiCd batteries are 2000 mAh and can be supplied with 5 A charging current in less than 1 / 2 hour load. On the green lawn flight is often the only car battery power source.For flight NiCd batteries with up to 7 cells (7 x 1.5 V, V = 10.5) is also good. With…
