An inrush current limiter is a component used to limit inrush current to avoid gradual damage to components and avoid blowing fuses or tripping circuit breakers. Negative temperature coefficient (NTC) thermistors and fixed resistors are often used to limit inrush current. NTC thermistors can be used as inrush-current limiting devices in power ...
A switched-mode power supply ( SMPS ), also called switching-mode power supply, switch-mode power supply, switched power supply, or simply switcher, is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently. Like other power supplies, an SMPS transfers power from a DC or AC source (often mains ...
Time-slot interchange. A time-slot interchange (TSI) switch is a network switch that stores data in RAM in one sequence, and reads it out in a different sequence. It uses RAM, a small routing memory and a counter. Like any switch, it has input and output ports. The RAM stores the packets or other data that arrive via its input terminal.
Sliding mode control. In control systems, sliding mode control ( SMC) is a nonlinear control method that alters the dynamics of a nonlinear system by applying a discontinuous control signal (or more rigorously, a set-valued control signal) that forces the system to "slide" along a cross-section of the system's normal behavior.
Push–pull converter. A push–pull converter is a type of DC-to-DC converter, a switching converter that uses a transformer to change the voltage of a DC power supply. The distinguishing feature of a push-pull converter is that the transformer primary is supplied with current from the input line by pairs of transistors in a symmetrical push ...
The Vienna Rectifier provides the following features: Three-phase three-level three-switch PWM rectifier with controlled output voltage [3] Three-wire input, no connection to neutral. Ohmic mains behaviour [4] Boost system (continuous input current) Unidirectional power flow [5] High power density. Low conducted common-mode electro-magnetic ...
When at least one of the inputs is low, transistor V 1 is turned on, V 2 is turned off, V 3 is turned on and V 4 off, pulling output voltage high. When both inputs are high, V 2 is on, V 3 is off and V 4 is turned on, pulling output low. A digital use of a push–pull configuration is the output of TTL and related families.
Power semiconductor device. A power semiconductor device is a semiconductor device used as a switch or rectifier in power electronics (for example in a switch-mode power supply ). Such a device is also called a power device or, when used in an integrated circuit, a power IC . A power semiconductor device is usually used in "commutation mode" (i ...
