Latest Patents
Toshinari's latest patents include advancements in piezoelectric transformer inverters. One of his inventions is a piezoelectric transformer inverter that can be driven across a wide range of input voltages and output currents. This capability allows for extensive dimming options while maintaining high efficiency, resulting in stable luminance. The design incorporates a piezoelectric transformer drive unit with conductive elements, switching elements, and a phase drive circuit. This circuit converts an inputted AC voltage into a lower frequency AC voltage for output to the piezoelectric transformer. Additionally, a phase-difference detecting unit monitors the phase difference between the drive controlling signal and the output current or voltage, providing a control voltage that optimizes performance.
Another patent describes a piezoelectric transformer inverter that performs voltage conversion of alternating voltage applied between primary electrodes. This invention includes a driving-frequency control unit that adjusts load current by changing the driving frequency of the piezoelectric transformer. A chopper unit is also integrated, which chops the input voltage at a frequency significantly higher than the driving frequency, allowing for precise control of the average input voltage. Furthermore, a dimming unit intermittently stops the driving frequency control unit, ensuring that the chopper unit can maintain its operation even during dimming periods.
