This paper presents performance analysis and simulation of maximum constant boost-control with third harmonic injection methods for the Z-source inverter, which can obtain maximum voltage boost for a fixed modulation index. The Z-source inverter is a recently invented a new power conversion concept mainly developed for fuel cell vehicular applications. The Z-source inverter is very advantageous over traditional inverters and it can be employed in all ac and dc power conversion applications. All traditional PWM methods can be used to control Z-source inverter. Maximum constant boost control methods eliminates the low-frequency ripples in the inductor current and capacitor voltage by maintaining the shoot-through duty cycle constant, and minimize the voltage stresses of switching devices at the same time. The Maximum boost control method is suitable for relatively high output frequency only, but in the maximum constant boost control method the Z-source network design is independent of the output frequency and determined only by the switching frequency. In this paper Z-source inverter parameters such as boost factor, output dc link voltage, capacitor voltage, output ac voLtage.
a. The pulse generator should be 3 arm.
(else as Ken mentioned a demux dimension mismatch will occur)
The reference sinusoids to the PWM generator has not accounted for 120" phase shift.
C. The logic implement for simple boost control does not check the condition for the negative limit of the envelop.
Hi thanks for creating the model, however can you advise what are the range appropriate values to key in the blocks like "internal_phase" and "internal" block. I keep getting dimension error at the demux.
