Frequency tracking ensures the piezoelectric transducer operates at the resonant frequency for maximum power output, and amplitude control regulates the mechanical motion of the output. This paper presents a novel driver based on a push–pull inverter for piezoelectric transducers. The proposed driver ...
PCLAMP is power dissipation of the limiting circuit of the rectifier output. The currents through inductor and transformer have periodic non-sinusoidal waveform. In that regard, we can separately analyze conduction losses in the windings caused by DC and AC currents [24]. For both CCM and DCM ...
Thus, data output is not the same, but significant data points are expected to be the same. The response ratio/ratio of mean (RoM) is largely unbiased, whereas the standardised mean difference, commonly known as Cohen’s d, may have non-negligible bias for small sample sizes [33] and ...
This induces a voltage in the secondary circuit of polarity defined by the point criterion (see Figure 1), which will allow current to flow through one of the branches (through diodes D1 or D2) to the output low-pass filter and the load R. Finally, during mode 3 operation, the ...
The waste energy dissipated at the output transistors of the AB-Class power amplifier is converted using thermoelectric generators. The creation of a thermoelectric setup is the first task in this work. The next task is to compare the performances of generators connected in different thermal ...
Calibration of the simulation output to the observed data used the PEST suite of software [32,33]. The graphical input/output software, Groundwater Vistas Version 8, was used for efficient model setup, simulations, calibration, and output visualization for PHT-USG and PEST. The same updated ...
An output-capacitorless low-dropout regulator (LDO) with a push–pull buffer was presented in this paper. The proposed push–pull buffer was able to provide a large charge and discharge current to increase the slew rate at the gate of the power transistor effectively, thereby improving the tran...
Figure 9a shows the small-signal intensity modulation responses of the DPPM-DFB laser, the PPM-DFB laser and the conventional DML at a constant output power of 12 mW. The bias currents 𝐼𝑏Ib for the single-sectional and dual-sectional DFB lasers are 50 mA and 84.5 mA, respectively. ...
where Vo is the average output voltage, Io is the average output current, and fs is the switching frequency. Figure 5. Voltage gain as a function of the duty cycle. One can obtain the theoretical value of the resonant inductance from (2). However, one must also incorporate the leakage ...
The output map showed regions with high to low suitability for Striga occurrence in the whole country (Figure 4). The model predicted a very high Striga asiatica suitability in areas around the Mbawa and Chitedze Research Stations, whereas it was moderate to low in the Chitala Research Station...
