2X60VOLT SMPS CIRCUIT SG3525 ETD44 IR2110 SCHEMATIC CIRCUIT DIAGRAM

A switched-mode power supply (switching-mode power supply, switch-mode power supply, switched power supply, SMPS, or switcher) is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently.

SMPS is an electronic power supply system that makes use of a switching regulator to transfer electrical power effectively. It is a PSU (power supply unit) and is usually used in computers to change the voltage to the appropriate range for the computer.12-Oct-2020

SMPS circuit SG3525 and IR2110 ICs drive MOSFETs in the installation primer on IRPF450 the transformer ETD44 feedback 4N33 provided with Opto Kublin output voltage 2 × 60-volt symmetrical ideal addition to the outlet for supplying amp are approximately 450W power TIP31 and TIP32 with transistors + – 12 volts regulated have solid preanfi tone control etc. You do not need to use an additional power supply to run such circuits.

There is a simple design of the circuit diagram and PCB drawing All parts can be found on the market in the testing stages 220v emi and the output filters are not critical parts that use the coils in pc power supplies make a robust system according to the situation 🙂

Separated portions in the circuit diagram you understand more easily so that the system such as TIP50 done with 13V control circuit, this circuit high voltage (primary) section + output connected SG3525 SMPS control integrate the feeding respectively providing the first operation after the start ETD44 is wound on three out of the winding laps It is regulated by 24v DV 7812 and continues to feed the control part SG3525.

In many SMPS designs, this method can be used as a circuitry with a transistor-controlled circuit. Note, however, that these systems are not strong enough to feed the entergate, so additional feed should be fed as additional feed winding or control with a normal transformer of 2..3 watts as described above. Anyway, we started off with the start circuit used in SMPS circuits 🙂
