Here, two controllers exchange data (in blue), while acting on their own state variables through dedicated feedback loops (in red). A back-to-back configuration often involves a grid-tied rectifier, which controls the DC bus voltage to which an inverter is connected.
Such converters are commonly employed in wind energy systems, HVDC links, and industrial variable frequency drives to enable bidirectional power transfer and regenerative operation. A back-to-back converter consists of two three-phase converters, typically an AC/DC rectifier stage and a DC/AC inverter stage, connected via a common DC link.
A variable power factor back-to-back inverter test method has been proposed earlier, but the method doesn''t go far enough to accurately emulate the motor currents in an EV powertrain where the non-linearities of the IUT and motor are not taken in account .
Back-to-back inverter circulating test setup. [...] testing system consists of two back-to-back inverters with inductor load connected in between, as shown in Fig. 1. The basic idea is to adjust the voltage vectors of the two backto-back connected inverters so that magnitude and phase angle of the voltage across inductor loads can be changed.
