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.

Can a high-frequency variable load inverter directly drive widely variable loads?

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.

Can a single switch resonant inverter be used at fixed frequency?

VI. CONCLUSION This paper presents a methodology for rapidly synthesizing single-switch resonant inverters such as Class E inverters for operation at fixed frequency with variable load resistance (i.e., with load modulation). We present a design methodology yielding class E inverter designs that are effective across a wide load resistance range.

Are class E inverters effective across a wide load resistance range?

We present a design methodology yielding class E inverter designs that are effective across a wide load resistance range. We focus on identifying the resonant frequencies and characteristic impedances of the key resonant networks in the circuit, and provide guidance of how circuit performance is modified by adjusting these parameters.

What is the operating frequency of an inverter?

At the operating frequency of the inverter, 13.56MHz, this current is of similar magnitude to the desired output current and represents a signi cant loss mechanism. Therefore, there it is desirable to have a device with both low on resistance and low output capacitance.

What is the ciency of a RF inverter?

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. ciency of 95.4%.
