Generate pulses for SVPWM-controlled three-level converter

**Library:**Simscape / Electrical / Specialized Power Systems / Power Electronics / Power Electronics Control

The SVPWM Generator (3-Level) generates pulses for three-phase three-level Neutral-Point-Clamped (NPC) converters. The block generates twelve pulses using the space vector pulse width modulation (SVPWM) technique.

The neutral-point voltage deviation is controlled by a proportional regulator using two DC voltages, as well as the DC current flowing in or out of the DC link. The defining equation is

$${V}_{out}=m\cdot \frac{{V}_{dc}}{\sqrt{2}},$$

where:

*V*is the line-to-line rms voltage generated by the NPC._{out}*m*is the modulation index and 0 <*m*< 1.*V*is the DC current flowing in or out of the DC link._{dc}
