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 ...
A capacitor voltage transformer (CVT), is a transformer used in power systems to step down extra high voltage signals and provide a low voltage signal to the actual VT (voltage transformer) used for operating metering/protective relays due to a lower cost than an electromagnetic PT. The circuit diagram for a simple capacitor voltage transformer
A variable-frequency transformer is a specialized three-phase power transformer which allows the phase relationship between the input and output windings to be continuously adjusted by rotating one half. They are used to interconnect electrical grids with the same nominal frequency but without synchronous phase coordination.
An example of an application of an autotransformer is one style of traveler's voltage converter, that allows 230-volt devices to be used on 120-volt supply circuits, or the reverse. An autotransformer with multiple taps may be applied to adjust the voltage at the end of a long distribution circuit to correct for excess voltage drop; when ...
Basic parts of an outboard motor. An outboard motor is a propulsion system for boats, consisting of a self-contained unit that includes engine, gearbox and propeller or jet drive, designed to be affixed to the outside of the transom. They are the most common motorised method of propelling small watercraft.
Delta – A 'delta' or 'phase to phase' transformer is used on a delta distribution circuit. A single-phase delta transformer has two bushings connected to two of the three primary wires, so the primary winding sees the phase-to-phase voltage; this avoids returning primary current through a neutral that must be solidly grounded to keep its ...
Buck–boost transformers can be used to power low voltage circuits including control, lighting circuits, or applications that require 12, 16, 24, 32 or 48 volts, consistent with the design's secondaries. The transformer is connected as an isolating transformer and the nameplate kVA rating is the transformer’s capacity. [2]
Unlike conventional transformers, a flyback transformer is not fed with a signal of the same waveshape as the intended output current. A convenient side effect of such a transformer is the considerable energy that is available in its magnetic circuit. This can be exploited using extra windings to provide power to operate other parts of the ...
