| Abstract: | Switching power amplifiers have a wide range of applications in civil and military, such as electrical vibration test rigs and elec-tro-acoustic emission systems and many other important areas. A modular multi-level structure of high-power switching power amplifi-er and its working principle are studied in this paper. In addition, the thermal loss of the modular multi-level switching power amplifier is analyzed and the relationship between loss and power factor is discussed. According to the result of theoretical analysis, the cooling system of equipment is designed. Then, the thermal system is simulated by software PLECS and finite element analysis software ANSYS. Finally, a 30kW modular multilevel switching power amplifier prototype is developed to verify the theoretical analysis and simulation results. |
