CHOPPER

A chopper is an electronic power DC convertor without an intermediate AC link giving a variable output voltage by varying the periods of conduction and non-conduction in an adjustable ratio.

COMBINED

A transformer that changes different quantities between circuits.

CURRENT

A transformer that changes the current between circuits.

FREQUENCY

A transformer that changes the frequency between circuits.

INVERTER

A transformer that converts from direct current (DC) to alternating current (AC).

RECTIFIER

A transformer that converts from alternating current (AC) to direct current (DC).

VOLTAGE

A transformer that changes the voltage between circuits.

USERDEFINED

User-defined type.

NOTDEFINED

Undefined type.

Last change: Improve definition split (#876) * bring back headers headers were previously removed by mistake, now bringing them back * add new lines and rename the tag add the word 'short' in it * unify newlines make exactly one newline before and two after the tag * resolving typos Because bringing back headers required to go back in time to previous version, I'm now re-resolving the issues: #861, #860, #856 by ArturTomczak on 2024-07-16T16:07:28+02:00
