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.
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 high frequency power inverter includes two parts, main circuit and control circuit. The main circuit includes an inverter DC power supply, high frequency high voltage transformers, IGBT bridge inverter, protection circuits, high frequency high voltage silicon stack (Rectifier) , etc.
The high-voltage inverter converts direct current (DC) from the batteries or generator to alternating current (AC) to power the drive motors. The high frequency power inverter includes two parts, main circuit and control circuit.
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.
