Analysis and Design of a Multi-Tapped High-Frequency
Abstract—The Google Little Box Challenge, an open competition to build the world smallest 2 kW Photo-Voltaic (PV) inverter, triggered a trend in the power electronic community
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.
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.
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%.
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 1000W point represents the maximum power output of the system that was validated in testing. As can be seen in waveform (e) inverter B does not fully achieve full zero voltage switching, switching instead with around 50V on the transistor. However, the e ciency data shows that this has little impact on performance.
The power supply topologies suitable for the High-Frequency Inverter includes push-pull, half-bridge and the full-bridge converter as the core operation occurs in both the quadrants, thereby, increasing the power handling capability to twice of that of the converters operating in single quadrant (forward and flyback converter).
