1.5 A 280 kHz/560 kHz Boost Regulators
... syncing up to 1.8 times the base oscillator frequency. As shown in Figure 28, in order to sync to a higher frequency, a positive transition turns on the power switch before the output of the oscillator goes high, thereby resetting the oscillator. The sync operation allows multiple power supplies to ...

THE SWITCHING BEHAVIOUR OF AN IGBT IN ZERO CURRENT
... first flows through the IGBT. This causes a removal of positive charge carriers in the drain sided pn-junction until the IGBT becomes reverse biased and the turn-on process of the diode begins. The closing overvoltage of the diode can be seen in the voltage waveform of UDS. This overvoltage is extra ...

Switch
In electrical engineering, a switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another.The mechanism of a switch may be operated directly by a human operator to control a circuit (for example, a light switch or a keyboard button), may be operated by a moving object such as a door-operated switch, or may be operated by some sensing element for pressure, temperature or flow. A relay is a switch that is operated by electricity. Switches are made to handle a wide range of voltages and currents; very large switches may be used to isolate high-voltage circuits in electrical substations.
