Abstract
DC power supply required for 12 kW solid-state RF power amplifier (SSPA) is designed and analyzed. Rating (30–65 V, 320 A) and topology of power supply are derived to satisfy load requirement. The selected topology is twelve-pulse rectifier followed by interphase transformer and synchronous buck converter to get desired output voltage. Modular design is selected to minimize copper losses, to reduce the voltage drop and to optimize the resources available. Simulation is done using PSIM software to analyze the performance in entire operating range and validation of the design. Prototype model is developed with same voltage range (30–65 V) but lower current rating (10 A). Testing is done at different voltage and current levels to analyze steady state and dynamic performance. The simulation and experimental results are in good agreement.
