| Résumé | This paper introduces a new kind of piezoelectric DC-DC converter. A ceramic is used as an energy storage element to replace the traditional inductance. Once resonating, the system describes a cycle at each resonance period taking energy to the source, storing it temporarily and transmitting it to the load with soft switching. A resonator suitable for the converter is presented and characterized with an electrical equivalent model. A simulation representing the whole system, gives very attracting results with very high efficiency for different output powers. The converter was tested and fully validated by experimental works. An efficiency of 85 percent was reached for a 10-20 volts step up converter with an output power of 500 milliwatts. © 2018 IEEE. |
