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.
A frequency changer or frequency converter is electronic or electromechanical equipment that converts alternating current of one frequency to alternating current of another frequency. The equipment may also change the voltage , but if it does, that is incidental to its principal purpose, since voltage conversion of alternating current is much ...
MDC (Motorola Data Communications), also known as Stat-Alert, MDC-1200 and MDC-600, is a Motorola two-way radio low-speed data system using audio frequency shift keying, (AFSK). MDC-600 uses a 600 baud data rate. MDC-1200 uses a 1,200 baud data rate. Systems employ either one of the two baud rates.
In electronics, a frequency multiplier is an electronic circuit that generates an output signal which has a frequency that is a harmonic (multiple) of its input frequency. Frequency multipliers consist of a nonlinear circuit that distorts the input signal and consequently generates harmonics of the input signal.
Flat no-leads packages such as quad-flat no-leads (QFN) and dual-flat no-leads (DFN) physically and electrically connect integrated circuits to printed circuit boards. Flat no-leads, also known as micro leadframe (MLF) and SON (small-outline no leads), is a surface-mount technology , one of several package technologies that connect ICs to the ...
