FAQS 4

How to control a three-phase inverter?

The PWM control technique is the most effective control scheme for controlling the three-phase inverter. In this proposed method, carrier-based PWM schemes are used such as PD, POD, and APOD have been applied. These are also called constant frequency techniques; generation switching pulses for an N level inverter, an N − 1 carrier is required.

Can MC-PWM control a three-phase parallel inverter?

In this article, the three-phase parallel inverter can be controlled by MC-PWM (APOD, POD, and PD). The inverter performance can be evaluated in terms of THD. The block diagram of the proposed system is shown in Fig. 1. The proposed inverter circuit includes three single-phase five-level inverters.

What is a three-phase five-level inverter?

Three single-phase five-level inverters are given to the 12 terminal of the three-phase transformer, and the neutral points are shorted. The key merits are that it obtains a higher output voltage with a reduced number of active devices, transformer, DC input source, and simplified control circuits.

What is a discrete model of paralleled 3p2l inverters?

(1) The discrete model of paralleled 3P2L inverters is established, based on which the improved control scheme is designed in detail. The output variables of the controllers for circulating current suppression are directly generated by the modified model, while the tedious tuning process for control parameters is avoided.
