What is a high frequency variable load inverter architecture?
This thesis presents a high frequency variable load inverter architecture along with a physical prototype and e ciency optimizing controller. The inverter architecture consists of two constituent inverters, one connected directly through the load and the other connected through an immittance converter, which acts as a lossless power combiner.
What is a high frequency inverter?
In many applications, it is important for an inverter to be lightweight and of a relatively small size. This can be achieved by using a High-Frequency Inverter that involves an isolated DC-DC stage (Voltage Fed Push-Pull/Full Bridge) and the DC-AC section, which provides the AC output.
Is a new inverter architecture suitable for varying load impedances?
Abstract: This paper presents a new inverter architecture suitable for driving widely varying load impedances at high frequency (HF, 3-30 MHz) and above. We present the underlying theory and design considerations for the proposed architecture along with a physical prototype and efficiency optimizing controller.

From these results it is evident that the HFVLI prototype is successful in the goal of driving a wide load range at high power power levels. rst physical prototype of of a wide load range RF inverter based on the proposed high frequency variable-load inverter topology was designed and built along with an e ciency optimizing controller.
How do hfvli inverters work?
The HFVLI system requires two inverters having adjustable relative phases and independently adjustable output voltages and an immittance converter. To reduce the prototype complexity, it was decided to utilize controllable lab power supplies to provide supply modulation. Here we detail the design of the constituent inverters and associated output
