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.
A low-dropout regulator ( LDO regulator) is a type of a DC linear voltage regulator circuit that can operate even when the supply voltage is very close to the output voltage. [ 1] The advantages of an LDO regulator over other DC-to-DC voltage regulators include: the absence of switching noise (in contrast to switching regulators ); smaller ...
A tower type UPS with one IEC 60320 C14 input and three C13 outlets. A large data-center-scale UPS being installed by electricians. An uninterruptible power supply ( UPS) or uninterruptible power source is a type of continual power system that provides automated backup electric power to a load when the input power source or mains power fails.
July 11, 2024 at 6:12 PM. HOUSTON (AP) — About half a million Houston-area homes and businesses will still be without electricity next week, the city's largest utility said Thursday, stoking the ...
Bleeder resistor. In electronics, a bleeder resistor, bleeder load, leakage resistor, capacitor discharge resistor or safety discharge resistor is a resistor connected in parallel with the output of a high-voltage power supply circuit for the purpose of discharging the electric charge stored in the power supply's filter capacitors when the ...
Since the pandemic slowed, my team at Jotform has transitioned to working full-time in our offices. I’ve seen the benefits, in terms of learning, collaboration, innovation, and personal well-being.
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 is required and its ...
The prime purpose of foldback current limiting in linear power supplies is to keep the output transistor within its safe power dissipation limit. A linear regulator dissipates the difference between input and output voltages as heat. Under overload conditions, the output voltage falls, so the difference becomes larger, thus increasing dissipation.
