Abstract :
This paper discusses a frequency multiplying circuit, which consists of a multi-phase voltage-source inverter and multiple toroidal core. The principle of the frequency multiplying is to utilize the neutral point voltage fluctuation of the load. A multi-core transformer is used to obtain the voltage fluctuation. This paper discusses the design of the circuit, transformer and loss analysis of the proposed circuit. Besides, this paper clarifies the validity of the proposed converter in terms of simulation and experimental results.
