How to control output power of a backto-back connected inverter?
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. In this way, the output power of Inverter 1 and power factor angle can be controlled. The concept is shown in Fig. 2, where V 1 and V 2 are the two voltage
Does a variable power factor back-to-back inverter test work?
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 .
What is back-to-back inverter circulating test setup?
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.
Can a synchronverter control a back-to-back system?
This study presents an innovative approach where both sides of a back-to-back (BtB) system are controlled using the synchronverter approach, allowing to control the power transfer through the converters as it would be in a real motor–generator pair system.
How do inverters work?
The control of the inverter is subdivided into 2 parts. First, a closed-loop controller regulates the bus voltage by drawing current from the grid. Second, this grid current is controlled in the stationary reference frame, with an additional term for the active damping of the LCL filter. The relevant documentation is given below:
What is a synchronverter in a power converter?
The synchronverter approach is used to control the power converters like a VSG without the use of a PLL circuit. A synchronverter include the mathematical model of an ideal synchronous machine, including a virtual primer control (virtual mechanical torque), as well as a virtual excitation voltage (virtual voltage regulator).
