An accurate back to front design methodology for PT based load resonant converters

In this work a standard design methodology with high accuracy and suitable for different PT (Piezoelectric-Transformer) based load resonant converters has been developed. With this methodology, a complete converter parameter design, optimization or even PT parameter evaluation can be done in a short time. The necessary inputs of the design flow are the specifications of the converter, such as minimum input voltage, switching frequency, output voltage and output power, based on which the PT will be designed first. The output of the design flow is an appropriately designed input inductor, which meets the requirement of the specification. This design method can help designer to avoid repetitive simulations and generate optimized design parameters.
