Abstract
Hysteresis feedback controlled synchronous buck converter-based power supply is designed and developed for biasing the transistors of Solid State RF Power Amplifier (SSPA). Design verification is done using PSIM software. The RF power requirement of SSPA varies from a few watts to 12 kW depending on RF application. It requires the power supply to have constant voltage and variable current. A comparative study of fixed frequency pulse width modulated (PWM) power converters and variable frequency hysteresis control power converter has been done. The advantages and challenges involved with hysteresis control are discussed. To operate SSPA, a 30–65 V, 320 A power supply is needed but to validate the power supply topology along with the controller, a prototype power supply developed with the same voltage rating and lower current rating of 10 AModular design is selected and operated with two parallel modules. The steady state and dynamic response are analyzed. Experimental and simulation results are in good agreement.
