Another issue of the three-phase inverter is the common-mode voltage (CMV), which is excited by the switching behavior of the power semiconductor devices .
The control parameters are directly obtained by the discrete model. The configuration of carrier phase is optimized to reduce common-mode voltage. The paralleled configuration of three-phase two-level (3P2L) inverters has been put forward to increase the output power rating, operating efficiency, and system reliability.
The study has been carried out on a system consisting of two three-phase inverters sharing the same DC input link and connected in parallel to a balanced three-phase resistive load without galvanic isolation, as shown in Fig. 1. The inverters are VSI [2,17], with SVPWM modulation [9,15,21,28,32-33].
(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.
Our standardized container products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
