If overmodulation occurs, the output voltage of the power converter clamps to the positive or negative DC rail. In the Three-Phase Two-Level PWM Generator example, the Two-Level Controller subsystem contains a 400–V DC-link input, and a modulation index, m, of 0.8. For SPWM, the maximal...
This block allows you to choose natural, symmetric, or asymmetric sampling of the modulation wave. ThePWM Generator (Five-phase, Two-level)block does not perform carrier-based PWM. Instead, the block uses input signals to calculate gating times and then uses the gating times to generate both ...
Using the continuous phase modulation framework [92], which is commonly used in aeronautical telemetry [93], deep-space communications [94], and the Bluetooth wireless standard [95], a PCFM radar waveform implementation has been developed [46,47] that converts an arbitrary polyphase code [θ0...
