What is a dual inverter (di)?
The Dual Inverter (DI) with galvanically isolated DC supplies offers advantages such as multilevel and fault-tolerant operation, superior DC voltage utilization, and simple control, making it particularly attractive for traction applications.
Why do inverters switch from single to dual inverter operation?
Single inverter operation to Dual inverter operation due to the increase in rotational speed, switching from Single inverter operation to Dual inverter operation due to the decrease in torque, and switching from Dual inverter operation to Sin-gle inverter operation due to the increase in torque.
Is a DC-AC inverter based on a dual-active-bridge converter?
Based on the commonly used two-stage isolated inverter, this study proposed a novel DC–AC inverter that combines dual-active-bridge (DAB) converter, switched capacitor and full-bridge inverter. Utilising the strategy of phase-shift shoot-through control, DAB will generate a high-frequency pulse DC link cooperated with switched capacitor.
Can a full-bridge inverter achieve zero-voltage switching?
As a result, during the shoot-through period, when the DC link is in zero-voltage-stage, the full-bridge inverter could realise zero-voltage switching (ZVS) through discrete pulse modulation. Principles, characteristics and implementations of the proposed inverter and its control strategy are analysed in detail.
What is a bidirectional isolated DC–AC inverter?
Bidirectional isolated DC–AC inverters are widely used in industrial applications, such as grid-connected uninterruptible power supply, renewable power energy system, electric vehicles and so on. In order to improve the conversion efficiency, realising soft switching will become the essential technology in the research of DC–AC inverters.
Can a multi-level inverter be used if a battery fails?
In the case of a battery failure, it can be operated as a multi-level inverter by controlling the voltage of the smoothing capacitor on the failure side to half of the battery voltage, and improvement in system e -ciency can be expected.
