description: This work is dedicated to the modification of existing circuit designs of switch-mode power supplies based on a widespread UC384x series of PWM controllers. The purpose of this work is to develop an universal secondary power supply with a wide range of output voltage adjustment and to place its components on a printed circuit board with dimensions 9x12 cm.
Tasks that were solved in this work:
1. Selection of circuit topology for the power supply;
2. Calculation of circuit elements and selection of components;
3. Working capacity test of the circuit by its simulation in Micro-Cap;
4. PCB trace of the device.
As a result of this work a flyback switch-mode power supply using AC power 220 V Â± 20% as a source, with output voltage adjustment ranged 14 Ã· 28 V, maximum output power 180 W and estimated efficiency â 85,4% was developed.
Scope: Supplying power to a wide range of electronic devices.
Conclusion: The task for the final qualification work is fully completed.
