Design of the fixed frequency controlled piezoelectric transformer based DC/DC converter


Piezoelectric transformers (PTs) converters show some difficulties to work in the case of the variable load at fixed frequency. PTs can be designed to achieve these problems, but the size of the PT may become larger. In fact, the selection of the circuit topologies and the control methods influence the size and the efficiency of the PT converter. Two… (More)
