FAQs about Inverter back voltage and current
How does a back-to-back inverter work?
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.
Are voltage source type inverters easier to control?
Voltage source type inverters are easier to control than current source type inverters. It is easier to obtain a regulated voltage than a regulated current, and voltage source type inverters can directly adjust the voltage applied to a load by varying the conduction ratio (i.e., the pulse width of a PWM signal).
How to control the output of an inverter?
Firstly, different control strategies are usually used to control the output of the inverter to solve the asymmetry problem caused by the three-phase asymmetric load when the back-to-back converter supplies power to the load. Common control strategies include d / q instantaneous control and symmetrical component component control.
What is a current source type inverter?
Current source type inverters control the output current. A large-value inductor is placed on the input DC line of the inverter in series. And the inverter acts as a current source. The inverter output needs to have characteristics of a voltage source.
What is a voltage source inverter?
The inverter is known as voltage source inverter when the input of the inverter is a constant DC voltage source. The input to the voltage source inverter has a stiff DC voltage source. Stiff DC voltage source means that the impedance of DC voltage source is zero. Practically, DC sources have some negligible impedance.
Which control strategy leads to asymmetric output voltage when back-to-back converter is used?
The existing control strategy may lead to asymmetric output voltage when back-to-back converter is used to supply unbalance load. Usually, an inner loop d / q decoupling controller, a constant DC voltage controller of the rectifier side, and a constant AC voltage controller of the inverter side are established.
