A dual inverter feeding an open-ended motor load is a feasible solution for high-power traction applications. The topology supplied from isolated DC sources has a power-sharing capability. Different pulse width modulation (PWM) techniques have been proposed for the dual inverter. The performance of these modulation schemes can be compared by analysing the current ripple output of the dual inverter drive. There are various methods in the literature to analyse the ripple content in the output current of the dual inverter. However, the existing work on ripple analysis has been done only for equal power sharing between the isolated DC sources. This study presents an output current ripple analysis for carrier-based PWM techniques for different power-sharing ratios. The variation in the current ripple with varied power-sharing ratios for different PWM techniques is demonstrated. The results to validate the analysis have been obtained using MATLAB/Simulink and real-time simulator. Based on the discussion, an optimal PWM technique under different sharing conditions has been identified.

“…With the proposed method, the SOCs of the two battery pack‐based voltage sources can be controlled to be balanced dynamically, by re‐distributing the reference voltage into two inverters. Compared with the method in [4], the conventional modulation process is not modified and can be directly applied in the proposed method. As a result, the proposed method is easier to implement and can be extended to many existing literatures directly.…”

“…However, in actual applications, such as electric vehicular system, the system power would be supplied by the voltage source composed of battery packs, in which the power of the supply is limited and consequently its power control has to be considered to avoid the unbalanced discharge. On this basis, an instantaneous power balancing technique is proposed for an open-winding induction machine in [4], by shifting the modulating signals of the two inverters synchronously according to the state of charges (SOCs) of the battery connected to the different dc bus. However, it is achieved based on the modification of the conventional modulation process, which complicates its implementation and can be further improved.…”

In open‐winding permanent magnet synchronous machine (OW‐PMSM) applied in electric vehicular system, two voltage sources composed of battery packs are applied. For safety and better performance, the over‐discharge on one of these two voltage sources should be avoided and their state of charges (SOCs) should be controlled in balance. On this basis, a reference voltage redistribution‐based control scheme is proposed to balance the SOCs of OW‐PMSM system in this letter, which utilizes the SOCs of the two voltage sources to distribute the reference voltages into two inverters. With the proposed method, the SOCs of the two voltage sources can be controlled in balance dynamically, while the synthesis of the reference voltage is not affected. The performance of the proposed method is validated experimentally.
