The AN/PRC-77 entered service in 1968 during the Vietnam War as an upgrade to the earlier AN/PRC-25.It differs from its predecessor mainly in that the PRC-77's final power amplifier stage is made with a transistor, eliminating the only vacuum tube in the PRC-25, as well as the DC-DC voltage converter used to create the high plate voltage for the tube from the 15 V battery.
The power supply was required to have an output capacitive energy of less than 15.1 µJ and an inductive energy at disconnect of less than 5.3 µJ. [ 1 ] The standard defines an AC adapter to power devices requiring from 10 W to 130 W (~20 V × 6.5 A) or (extended voltage option) up to 240 W (60 V × 4 A). [ 2 ]
A simple voltage dropper can be used to reduce the voltage for low-power devices; if more than 12V is required, or for high-powered devices, a switched-mode power supply is used. The output will usually be DC in the range 1.5–24 V. Power supplies that output either 100–120 V AC or 210–240 V AC are available; they are called inverters ...
Mains electricity by country includes a list of countries and territories, with the plugs, voltages and frequencies they commonly use for providing electrical power to low voltage appliances, equipment, and lighting typically found in homes and offices. (For industrial machinery, see industrial and multiphase power plugs and sockets.) Some ...
HT Mobile was set up in 2007 as a joint-venture of Ministry of Health. [3] It was renamed to Vietnamobile in 2009, accompanied by the adoption of GSM technology to replace the less popular CDMA. [3] It started offering 3G services in late 2011, long after its major competitors. [1]
A power converter is an electrical device for converting electrical energy between alternating current (AC) and direct current (DC). It can also change the voltage or frequency of the current. Power converters include simple devices such as transformers, and more complex ones like resonant converters.
A multi-level converter (MLC) or (multi-level inverter) is a method of generating high-voltage wave-forms from lower-voltage components. MLC origins go back over a hundred years, when in the 1880s, the advantages of DC long-distance transmission became evident. [1] Modular multi-level converters (MMC) were investigated by Tricoli et al in 2017.
In 2013, U.S. Navy surveillance experts upgraded the G-BOSS system with DC-to-DC converters for power generation, having awarded Vicor Corporation a contract to improve the power systems. This upgrade package will include a 24-volt DC power electronics devices with 48-, 12-, and 9-volt DC outputs, 24-volt DC converters with 19.5-, 12-, and 48 ...
