AC- DC Power Supplies
AC-DC power supplies transform alternating current (AC) mostly from the mains supply into steady direct current (DC) power. They operate by rectifying the incoming AC voltage, smoothing out voltage fluctuations through filtering components, and regulating the DC output voltage to provide a stable and reliable power source for various electronic devices and systems.

Modern AC-DC power supplies might also incorporate advanced control circuitry, such as pulse-width modulation (PWM) controllers, to achieve high efficiency and precise voltage regulation. PWM involves rapidly switching the power supply output on and off, controlling the duty cycle to maintain the desired output voltage.
DC-DC Converters
A DC to DC converter is designed to take the voltage from a DC source (usually a battery) and converts the voltage of the supply into another DC voltage level. They can increase or decrease the voltage level. For example, it might be necessary to step down the power of a large battery of 24V to 12V to power a radio.

DC-DC conversion can employ either electronic or magnetic methods. Electronic conversion uses switching technology, temporarily storing input energy and releasing it at varying voltage outputs using components like inductors and capacitors. Magnetic conversion involves periodic energy storage in a magnetic field, released within a frequency range by adjusting charging voltage duty cycle for load power control.
Inverters (DC to AC)
They transform direct current (DC) power into alternating current (AC). Use high-frequency switching techniques using semiconductor devices like MOSFETs or IGBTs. These devices modulate the DC input through a series of switching pulses, generating an AC waveform that closely resembles utility-supplied electricity.

In renewable energy systems like solar photovoltaics, they enable the conversion of DC output from solar panels into usable AC power, suitable for integration with the grid or direct consumption. In industrial applications, inverters play a crucial role in controlling the speed and torque of AC motors, optimizing energy-efficient motor operation and enhancing overall process control. DC-AC inverters seamlessly provide power from DC sources to of AC-dependent devices.
