Comparative analysis between the switch mode power supply (SMPS) using IC Tl494cn transformer based on power supply linear

Abstract In general Audio Amplifier using linear transformer-based power supply as energy conversion. Such use may cause interference with electrical installation sourced from the substation circuit. The non-linear load would cause problems in the electrical installation system. This research shows that Switch Mode Power Supply (SMPS) has a minimum voltage Vdrop output load of about 100 to 33.33 ohms. On the burden of 25-20 ohms as the voltage Vdrop output, which is different from Linear Power Supply Transformer-based parameters, that its voltage Vdrop output was changed significantly.
