  2. Power semiconductor device - Wikipedia

    en.wikipedia.org/wiki/Power_semiconductor_device

    Switching times range from tens of nanoseconds to a few hundred microseconds. Nominal voltages for MOSFET switching devices range from a few volts to a little over 1000 V, with currents up to about 100 A or so, though MOSFETs can be paralleled to increase switching current. MOSFET devices are not bi-directional, nor are they reverse voltage ...

  3. MOSFET - Wikipedia

    en.wikipedia.org/wiki/MOSFET

    This analog switch uses a four-terminal simple MOSFET of either P or N type. In the case of an n-type switch, the body is connected to the most negative supply (usually GND) and the gate is used as the switch control. Whenever the gate voltage exceeds the source voltage by at least a threshold voltage, the MOSFET conducts.

    ON/OFF Control: Typically used for heating loads or speed control of motors, this control method involves turning the switch on for n integral cycles and turning the switch off for m integral cycles. Because turning the switches on and off causes undesirable harmonics to be created, the switches are turned on and off during zero-voltage and ...

  6. Thyristor - Wikipedia

    en.wikipedia.org/wiki/Thyristor

    A thyristor (/ θ aɪ ˈ r ɪ s t ər /, from a combination of Greek language θύρα, meaning "door" or "valve", and transistor [1]) is a solid-state semiconductor device which can be thought of as being a highly robust and switchable diode, allowing the passage of current in one direction but not the other, often under control of a gate electrode, that is used in high power applications ...

  7. Transmission gate - Wikipedia

    en.wikipedia.org/wiki/Transmission_gate

    A transmission gate (TG) is an analog gate similar to a relay that can conduct in both directions or block by a control signal with almost any voltage potential. [1] It is a CMOS-based switch, in which PMOS passes a strong 1 but poor 0, and NMOS passes strong 0 but poor 1.

  8. Solid-state relay - Wikipedia

    en.wikipedia.org/wiki/Solid-state_relay

    A solid state relay (SSR) is an electronic switching device that switches on or off when an external voltage (AC or DC) is applied across its control terminals. They serve the same function as an electromechanical relay , but solid-state electronics contain no moving parts and have a longer operational lifetime.

  9. Insulated-gate bipolar transistor - Wikipedia

    en.wikipedia.org/wiki/Insulated-gate_bipolar...

    The IGBT combines an isolated-gate FET for the control input and a bipolar power transistor as a switch in a single device. The IGBT is used in medium- to high-power applications like switched-mode power supplies, traction motor control and induction heating.
