Active PFC supported SMPS power supply is made with IR2156 Ballast driver integrated circuit. Active PFC section uses MC33262 active power factor integrated circuit. Output voltage of SMPS circuit on load is 2X40VDC PFC output voltage is 400V There is source PCB drawing of Active PFC Power supply project (sprint layout 6) also MC33262 PFC…
I don’t know about ultrasonic welding for plastic, but there are projects that can be useful for those who are interested. The appropriate ultrasonic with sufficient power in the application is 60W at 68kHz, disassembled from an ultrasonic cleaner. A lower frequency is more suitable. PVC welding The ultrasonic transducer behaves approximately like a series…
I prepared a PCB for the Simple Switch Mode Power Supply Self Osc ATX Transformer that I shared before. It is compatible with the battery boxes of many drills. Apart from the PCB design, the tests were very challenging, I encountered interesting problems and saw strange events especially in electronics repair work. The problem of…
An SMPS switched power supply project for power amplifiers with the IR2156 half-bridge mosfet driver IC from International Rectifier (currently acquired by Infineon Technologies). Brief information about IR 2156. The IR2156 is a half-bridge half-bridge converter controller with a built-in high voltage driver and a programmable oscillator. It was designed by the manufacturer as a…
1200W 60V SMPS Power supply UC3844 Classic topologies of blocking converters are usually considered suitable only for small ones performance, on the order of about 100-200 W. Their main advantage for low-power applications is simplicity and large input voltage range. At the output of the transformer only the rectifier diode and the output capacitor are…
Simple SMPS Circuit Self-Oscillating ATX Transformer There were shares to run the rechargeable drill without a battery IR2153 SMPS, Battery, Transformer.. The batteries of the drill I used were also faulty, the price of the battery pack was quite high, by connecting a 12v 7ah battery, I used the drill for a long time, but…
2X84V 2X35V 14V 220W 300W 1000W SMPS circuits based on the SG3525 PWM control IC have been designed with a 14v output of the 300W output, and the SG3525 current limiting circuit is also shared for battery charging. The design of the circuits is tidy in the simple PCB drawings, but the PC40 toroidal ferrite…
I shared many SMPS circuits made with IR2153. IR2153 is especially suitable for use in amplifier power supplies, even in power amplifiers in large companies, in mixers Power supply uses IR2153 on the SMPS floor. (Yamaha EMX5000 mixer service manual ir2153) I have been working on the SMPS circuit I have applied for a long…
The 0.2V-80V switched power supply built on TL494 Integration can be used in various devices, motors, battery, battery charging processes, etc. designed for. There is additional SMPS circuit with TNY267 integrated circuit for feeding elements such as TL494, Fan, Relay. Like many circuit elements used in the SMPS Project, this material was supplied from PC…
SMPS designs designed as IR2153 amplifier power source based on IR2153 Integration. The 300W version gives 2X44V DC. Circuits have Short circuit protection. IR2153 SMPS 300W Version: In general, IR2153 Supply voltage is taken over 220v filter capacitor, that is, over + 310V resistor or mosfet regulator. In these circuits, 18k 2w resistor is connected…
