Summary for: SpaceVectorModulator < Modulator

Class summary

SpaceVectorModulator Prototype multiphase space vector modulator.

Based on the paper ‘Multilevel Multiphase Space Vector PWM Algorithm’

this = SpaceVectorModulator(UDC, fs)

Supports an arbitrary phase count and number of levels >=2

Properties

.Mave Averaging matrix for 3rd harmonic injection.

Third harmonic injection is realized with the formula Delta = (max( this.Mave.*Uphase_ref,[],1 )' + min(this.Mave.*Uphase_ref,[], 1)') / 2; Uphase_with_injection = Uphase_ref - this.Mave*Delta;

By default, this.Mave = ones(this.phases, 1); but setting a different matrix can be used to account for e.g. two independent star points in a 6-phase system.

.UDC DC-link voltage

.Uref Target voltage in dq-frame.

.f Fundamental frequency.

.fs Switching frequency.

.levels Number of voltage levels.

Defaults to 2.

.phases Number of phases.

Defaults to 3.

.recompute Recompute switching times for the next switching period.

recompute(this, t)

.RESET Reset graphics object properties to their defaults.

RESET(H) resets all properties having factory defaults on the object identified by handle H to their default values. If h is a figure, MATLAB does not reset PaperPosition, PaperUnits, Position, Units or WindowStyle. If h is an axes, MATLAB does not reset Position and Units.

For example, RESET(GCA) resets the properties of the current axis. RESET(GCF) resets the properties of the current figure.
