A single-phase, three-winding converter transformer. The converter transformers step up the voltage of the AC supply network. Using a star-to-delta or "wye-delta" connection of the transformer windings, the converter can operate with 12 pulses for each cycle in the AC supply, which eliminates numerous harmonic current components. The insulation ...
An enhancement of the six-pulse bridge arrangement uses 12 valves in a twelve-pulse bridge. [11] A twelve-pulse bridge is effectively two six-pulse bridges connected in series on the DC side and arranged with a phase displacement between their respective AC supplies so that some of the harmonic voltages and currents are cancelled.
CCV operation creates current and voltage harmonics on the CCV's input and output. AC line harmonics are created on CCV's input accordance to the equation, f h = f 1 (kq±1) ± 6nf o, [9] where f h = harmonic frequency imposed on the AC line; k and n = integers; q = pulse number (6, 12 . . .) f o = output frequency of the CCV
A resonant converter is a type of electric power converter that contains a network of inductors and capacitors called a resonant tank, tuned to resonate at a specific frequency. They find applications in electronics, in integrated circuits. [1] There are multiple types of resonant converter: Series resonant converter [2] Parallel resonant converter

It uses a high-frequency isolated DC-to-DC converter cascaded with a controllable full-bridge inverter that creates a small bipolar voltage in series with the line. The controller can control the power and compensate for accumulated voltage drop in a distribution line.
An American Rotary Phase Converter with a Transformer. A phase converter is a device that converts electric power provided as single phase to multiple phase or vice versa. The majority of phase converters are used to produce three-phase electric power from a single-phase source, thus allowing the operation of three-phase equipment at a site that only has single-phase electrical service.
ISO 7637 Road vehicles -- Electrical disturbances from conduction and coupling [1] is an international electromagnetic compatibility vehicle standard published by the International Organization for Standardization (ISO), that relates to 12- and 24-volt electrical systems.
