“…Because the merits of this device, the necessity of employing PT in the inverter circuit becomes more significant than ever. The PT can be represented by a capacitive load with nonlinear behaviors [3][4]. To confirm the effectiveness and reduce the losses of internal static capacitance, the development of a control strategy is highly suggested.…”

A hybrid-loop control approach applied to inverter circuit design with piezoelectric transducers is proposed in this paper. This approach was motivated because the transducer is easily affected by the temperature effect and damping pressure, causing the mechanical frequency drift and unstable current variation. In view of these demerits, a hybrid-loop control mechanism is suggested to achieve both phase-tracking and constant-current control such that both operation frequency and vibration strength can be well controlled while maintaining a stable mechanical frequency. Moreover, by embedding this hybrid control concept into microprocessor controller units without adding any further sensors devices, the design cost is found to be meanwhile reduced. To validate the feasibility of this approach, the method has been validated through mathematical analysis and hardware realization. Test results confirm the performance improvement of the approach for piezoelectric transducer applications.

“…A PT could be modeled as lumped components, shown in Fig. 1(a), near its resonance frequency [3]. The parallel capacitance C 0 is the parasitic capacitance in electrical domain, and the components R 1 , L 1 , and C 1 are equivalent models of a mechanical resonator in mechanical domain.…”

This paper presents a novel active damping control method for the driving circuit of a piezoelectric transducer (PT) applied in a distance measurement system. Since the vibration of the PT cannot come to a halt instantly after the driving circuit stops driving it, the minimum detectable length in the system with a single PT is restricted. By applying active damping, the transition time can be reduced. Conventionally, a peak detection circuit is needed to realize the active damping control. However, with the proposed control, the phase of the vibration can be known from the driving signal, and the active damping control can be realized without any sensing circuits. The proposed control method is verified with a bi-directional flyback converter. The experimental results show that the amplitude of terminal voltage of the PT can be reduced to one-fourth of the value with the conventional passive damping.
