Use of high frequency inverter in Gomel Belarus

This approach is well matched to the requirements of module integrated converters for solar photovoltaic (PV) applications. The topology is based on a series resonant inverter, a high frequency transformer, and a novel half-wave cycloconverter.

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.

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.

Typically a tunable matching network is used to transform the varying load into a ciency and impairing transient response. This thesis presents the design, physical prototype, controller, and experimental results of a high-frequency variable load inverter architecture (referred to as HFVLI) that can directly drive widely variable loads.

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

The thesis shows that the HFVLI topology is viable and presents a novel control strategy that can be used to optimize any system parameter than can be modeled and is broadly applicable to wide load range inverters based on power combining networks.
