Optimized low switching frequency modulation with neutral

The use of three-level converters with low switching frequency (SF) modulation is urgently needed for medium voltage high power applications. However, since it is not possible to frequently adjust the injected zero-sequence voltage and duty time of redundant vectors, the neutral point (NP) voltage problem of three-level converters becomes a tricky issue under low …

Frequency Modulation and Demodulation

Phase-Shift Keying(PSK):. In this modulation scheme, data is conveyed by changing or modulating the phase of a reference signal. PSK modulates a continuous wave (CW) carrier wave with an information signal and is distinct from amplitude-shift Keying, phase-shift keying, and frequency-shift Keying.

Frequency Modulation and Demodulation | SpringerLink

In frequency modulation we are interested in appropriate changing of instantaneous frequency of an oscillatory carrier according to the formula: f inst (t) = f c + Δf ⋅ x(t), where f c is nominal carrier frequency, x(t) is modulating function (signal), and Δf is modulation depth. Roughly speaking, we deliberately cause drift (fluctuation) of the carrier frequency …
