This paper describes the design, implementation, and characterization of an Electronics Power Conditioner (EPC) with dynamic drain bias control that maintains efficiency of PA over a range of output power levels. The Drain voltage of power devices is varied in a known fashion against the input RF drive variations dynamically, to obtain better efficiency values over a range of output power. As a consequence,...
Traveling Wave Tubes (TWTs) are extensively used in the satellite payloads as RF power transmitting amplifiers. TWT requires a highly sophisticated power supply; often known as High Voltage Electronic Power Conditioners (HV-EPC) in space community. Both the units put together make a Traveling Wave Tube Amplifier (TWTA). HVEPC is a regulated power supply used to provide conditioned and isolated voltage...
