Lab 2 Ohms Law

... The relationship between the electrical quantities current, voltage, and resistance is known as Ohm’s law. Essentially, voltage is proportional to current. The ratio between the voltage and current is the resistance. In this experiment, we will verify this relationship. Note that for some components ...

... How to Handle Non-Linear Loads on a Power Supply Non-linear loads, in the context of a power supply, are those that do not behave like an ideal resistor such as Point Of Load (POL) DC-DC converters and discharged capacitors that are switched onto the output causing high currents to flow until the ca ...

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.
