Inverter with load voltage

What is a voltage source inverter?

Voltage source inverters (VSIs) are commonly used in uninterruptible power supplies (UPS) to generate a regulated AC voltage at the output. Control design of such inverter is challenging because of the unknown nature of load that can be connected to the output of the inverter.

Which inverter has the most load current?

However, as can be seen in the system parameters for load (a), the majority of the load current is supplied by inverter A, which also experiences the majority of the losses. This disparity is due to the voltage dependent losses of the inverters.

How does a bridge inverter work?

The general concept of a full bridge inverter is to alternate the polarity of voltage across the load by operating two switches at a time. Positive input voltage will appear across the load by the operation of T1 and T2 for a half time period. The polarity of voltage across load will be changed for the other half period by operating T3 and T4.

How resonant inverter can achieve low voltage or current stress?

The low voltage or current stress across the switch can be achieved by the second-order resonant network. Furthermore, the common-ground Class E/F resonant inverter and its load-independent design procedure are introduced. Constant ac voltage output and zero-voltage switching can be achieved by the proposed inverter for a wide load range.
