hysteresis band in simulink

Licensee IntechOpen. The switching pattern of hysteresis inverters is produced through line current feedback and it is not pre-determined unlike the case, for instance, of Sinusoidal Pulse-Width Modulation SPWM where the inverter switching function is independent of the instantaneous line current and the inverter harmonics can be obtained from the switching function harmonics. The spectral characteristics such as the carrier frequency and frequency bandwidth are derived analytically and related to line parameters; it is a development useful in inverter-network harmonic interactions. The spectral characteristics of the line current under the fixed- and variable-band hysteresis control are compared in this section. Time, in s, between consecutive block executions.
