... Figure 2. Practical DC-DC up-converter using an LM2577. The diode from the fuse to ground is for reverse polarity protection and must be able to safely pass a current greater than that required to open the fuse. Note the 0.1µF bypass capacitor connected directly between pins 3 and 5 of the LM2577. ...

Summary presentation 12.2 alternating currents File
... Since both lamps are equally bright, the d.c. and a.c. supplies are transferring energy to the bulbs at the same rate. Therefore, the d.c. voltage is equivalent to the a.c. voltage. The d.c. voltage equals the r.m.s. value of the a.c. voltage. Notice that the r.m.s. value is about 70% (1/√2) of the ...

Power MOSFET
A power MOSFET is a specific type of metal oxide semiconductor field-effect transistor (MOSFET) designed to handle significant power levels.Compared to the other power semiconductor devices, for example an insulated-gate bipolar transistor (IGBT) or a thyristor, its main advantages are high commutation speed and good efficiency at low voltages. It shares with the IGBT an isolated gate that makes it easy to drive. They can be subject to low gain, sometimes to degree that the gate voltage needs to be higher than the voltage under control.The design of power MOSFETs was made possible by the evolution of CMOS technology, developed for manufacturing integrated circuits in the late 1970s. The power MOSFET shares its operating principle with its low-power counterpart, the lateral MOSFET.The power MOSFET is the most widely used low-voltage (that is, less than 200 V) switch. It can be found in most power supplies, DC to DC converters, and low voltage motor controllers.
