Half bridge SMPS circuit is a modified version of the ATX computer power supply circuit. Output power transformer ei33-rewound for symmetrical high voltage. Its power is 300 watts input voltage 240v ac output voltage + – 20volts + – 45volts adjustable. It can be used in ER34…ER35 transformers. You can only test the TL494 control…
Working with 24 volt motor driver circuit motor bike used with modified by attaching the TL494 control integrated circuit MOSFET driver transistors have three different versions of the system used is similar MOSFETs different 24V PWM Motor Control Circuit TL494 Motor Bike 24V Driver circuit schematic pcb files:
I shared earlier in the SMPS circuit Volt 250W 2×35 “13.8V 250W PC powersupply Modified” writing is almost the same system with the circuit. ATX psi modifying circuit has the advantage over other symmetrical and the primary section of the output MOSFET (IRF840) to be TL494 ATX Modified SMPS Circuit ATX power supply control integrated…
I’m dealing with a lot of computer power supply circuit arrangement made with EI33 transformer used almost all AT, ATX SMPS control IC TL494 psi resources found in SMPS output voltage operated 2X30 watt amp 140 volt power circuit TDA7294 made by 2 psi through bridge connections removed mono bass amp transformer windings distributed and…
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…
