Boost Converter Power Supply Steps:

Input Voltage: First, the boost converter receives an input voltage, usually from a battery or other DC power source.

Switching Operation: The switch in the converter (usually a transistor) opens and closes at a certain frequency, controlling the flow of current.

Energy Storage: When the switch is closed, the inductor stores energy; when the switch is opened, the inductor releases energy, working with the capacitor to provide an output voltage higher than the input voltage.

Output Voltage: By adjusting the duty cycle (the ratio of the switch-on time to the total period), the output voltage can be controlled.

Buck Converter Power Supply Steps:

Input Voltage: The buck converter also receives an input voltage.

Switching Operation: The switch opens and closes at a certain frequency, controlling the flow of current to the inductor and capacitor.

Energy Storage and Release: When the switch is closed, the inductor stores energy; when the switch is opened, the inductor and capacitor work together to maintain the flow of current to the load.

Output Voltage: By adjusting the duty cycle, the output voltage can be controlled to be lower than the input voltage.

General Power Supply Steps:

Power Source Selection: Select the appropriate power source based on the required voltage and current levels.

Circuit Design: Design the circuit to meet specific voltage and current requirements, including selecting the appropriate inductor, capacitor, and switching components.

Control Strategy: Implement an appropriate control strategy, such as pulse-width modulation (PWM) or pulse-frequency modulation (PFM), to regulate the operation of the switching components, thereby controlling the output voltage.

Protection Measures: Add protection measures such as overcurrent, overvoltage, undervoltage, and thermal protection to ensure the circuit operates safely under abnormal conditions.
