Power supply rejection ratio. In electronic systems, power supply rejection ratio ( PSRR ), also supply-voltage rejection ratio [1] ( kSVR; SVR ), is a term widely used to describe the capability of an electronic circuit to suppress any power supply variations to its output signal. In the specifications of operational amplifiers, the PSRR is ...
A power supply unit ( PSU) converts mains AC to low-voltage regulated DC power for the internal components of a desktop computer. Modern personal computers universally use switched-mode power supplies. Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the main voltage.
Keep Your Hands Off My Power Supply featured a different track-order. It also replaced "Cocky Rock Boys (Rule O.K.)" and "Razzle Dazzle Man" with the 1983 "My Oh My" B-Sides "Keep Your Hands Off My Power Supply" and "Can't Tame a Hurricane". "Run Runaway" was released first in America in March 1984.
In contrast, a linear power supply regulates the output voltage by continually dissipating power in the pass transistor. The switched-mode power supply's higher electrical efficiency is an important advantage. Switched-mode power supplies can also be substantially smaller and lighter than a linear supply because the transformer can be much smaller.
Examples of such systems include modern cell phones, with GND and voltages such as 1.2 V, 1.8 V, 2.4 V, 3.3 V, and PCs, with GND and voltages such as −5 V, 3.3 V, 5 V, 12 V. Power-sensitive designs often have multiple power rails at a given voltage, using them to conserve energy by switching off supplies to components that are not in active use.
Capacitive power supply. A capacitive power supply or capacitive dropper is a type of power supply that uses the capacitive reactance of a capacitor to reduce higher AC mains voltage to a lower DC voltage. It is a relatively inexpensive method compared to typical solutions using a transformer, however, a relatively large mains-voltage capacitor ...
Regulated power supply. A regulated power supply is an embedded circuit; it converts unregulated AC (alternating current) into a constant DC. With the help of a rectifier it converts AC supply into DC. Its function is to supply a stable voltage (or less often current), to a circuit or device that must be operated within certain power supply limits.
Half-power point. The half-power point is the point at which the output power has dropped to half of its peak value; that is, at a level of approximately -3 dB. [1] [a] In filters, optical filters, and electronic amplifiers, [2] the half-power point is also known as half-power bandwidth and is a commonly used definition for the cutoff frequency.
