| Video Discription | How to convert AC to DC using traditional Linear transformer Link : https://youtu.be/JXJaRPXPwjQ Switched-Mode Power Supplies (SMPS) are designed to address the challenges of traditional linear transformers by operating at much higher frequencies. This higher-frequency operation allows for the use of smaller coils (transformers and inductors) and reduces the size and weight of the power supply significantly. The key advantages of SMPS include: Higher Frequency Operation: SMPS use high-frequency switching techniques, typically in the kilohertz or megahertz range, compared to the low-frequency operation of traditional linear transformers (50-60 Hz). The higher frequency enables the use of smaller and lighter magnetic components, making SMPS much more compact and portable. Efficiency: SMPS are more efficient than traditional linear transformers. They minimize energy loss by switching the power to the load more efficiently, reducing wasted energy and heat generation. This efficiency contributes to longer battery life in mobile devices and lower energy consumption in other applications. Reduced Size and Weight: Due to the use of higher frequencies and smaller magnetic components, SMPS are considerably smaller and lighter compared to traditional linear transformers. This makes them ideal for portable electronic devices and applications where space and weight are critical factors. Regulation and Control: SMPS incorporate feedback control mechanisms to regulate the output voltage and maintain stability. This allows for precise voltage regulation even with fluctuations in input voltage or changes in load conditions. Wide Input Voltage Range: SMPS can often handle a wide range of input voltages, making them suitable for international use where mains voltages may vary. Flexibility and Versatility: SMPS technology can be adapted to different input and output voltage requirements, making it suitable for a wide range of electronic devices and applications. SMPS have become the standard choice for modern power supplies due to their higher efficiency, smaller size, and versatility. They are commonly used in mobile phone chargers, laptop adapters, desktop computers, LED drivers, and various other electronic devices where efficiency, size, and portability are crucial considerations. |
