Steps up the input voltage to a higher output level.
For AC-to-DC conversion, the input voltage is first rectified and filtered. Switch-Mode Power Supplies
High-frequency transformers or inductors for energy storage and voltage transformation. Steps up the input voltage to a higher output level
Different circuit configurations, or topologies, are used based on the desired output: Key Components Often a PWM controller like the
Includes Flyback and Forward converters, which use transformers to provide electrical isolation between input and output. 4. Comparative Analysis Switch-Mode Power Supply (SMPS) Linear Power Supply Efficiency High (75% to 98-99%) Low (25% to 50%) Size & Weight Compact and lightweight due to high-frequency components Large and heavy due to low-frequency transformers Heat Dissipation Low; remains cooler during operation High; requires significant heat sinking Noise & Ripple Higher electrical noise (EMI) and output ripple Very low noise and high stability Complexity High; requires specialized design and PCB layout Low; simpler circuit design 5. Key Components
Often a PWM controller like the TI TL598 that manages the switching cycles.
