    Power Electronics - Resonant Switching - Tutorialspoint

    An SMPS (switched mode power supply) refers to an electronic device that uses a switching regulator for the purpose of converting electrical power in an efficient manner. SMPS takes power from the main power lines and transfers it to a load. For example, a computer while ensuring the voltage and current characteristics are converted. When using the MOSFET as a switch we can drive the MOSFET to turn “ON” faster or slower, or pass high or low currents. This ability to turn the power MOSFET “ON” and “OFF” allows the device to be used as a very efficient switch with switching speeds much faster than standard bipolar junction transistors. Fig. 1 compares a conventional buck regulator with a version modified for ZVS operation. Utilizing the added phase, the ZVS type uses the clamp switch and circuit resonance to operate the high side (Q1) and synchronous (Q2) MOSFETs efficiently with soft switching, avoiding the losses they incur during conventional PWM operation and timing.

    Power Electronics - Introduction - Power Electronics refers to the process of controlling the flow of current and voltage and converting it to a form that is suitable for user loads. The most des Soft switching means you're using the inductor's "momentum" to pull the output low, when you open the high side switch. The low side switch is engaged after a "break before make" period that allows the output to swing to ground under its own power, just in time to prevent the current from taking parasitic diodes

    Switch Mode Power Supply - Basic Electronics Tutorials

    Buck Switch Mode Power Supply. The Buck switching regulator is a type of switch mode power supply circuit that is designed to efficiently reduce DC voltage from a higher voltage to a lower one, that is it subtracts or “Bucks” the supply voltage, thereby reducing the voltage available at the output terminals without changing the polarity. In other words, the buck switching regulator is a step-down regulator circuit, so for example a buck converter can convert say, +12 volts to +5 volts. In this Lecture i discussed the characteristics of ideal and practical switch. Then its classification on the basis of controlling,Blocking and direction of current flow.
