Output Characteristics

In order to decrease output micro-flux ripple wave characteristics of the piezoelectric driven micro-flux valve, it carried out research on piezoelectric ceramics driving power supply. In the research, it especially designed the low-voltage and high-voltage stabilizing circuit, small signal amplifying circuit and power amplifying circuit. By applying the power supply, the function signal would be amplified to a high-voltage output to drive the piezoelectric ceramics stack (PZT) to control displacement of the micro-flux valve’s spool, and then realize precise control the micro-flux of the valve. At last, it carried out experimentations on the output characteristics of the power supply, and the experimental results proved the output signal of the power supply have excellent input-output linearity and small ripple wave characteristics, and the high-voltage output ripple wave error is less than 10mV. More over, it used the power supply to drive an 8×8×20mm PZT with capacitance 2.3, and measured the quickly discharging characteristics. The results prove the quickly discharging time is only 10.10ms when the driving voltage is 180V, which means the power supply has excellent quickly discharging characteristics.

Voltage Stress

In this paper, a soft-switched boost converter including an integrated dual half-bridge circuit with high voltage gain and continuous input current is introduced that can be suitable for the applications requiring a wide voltage gain range, such as for the front-end of the inverter in a DC microgrid to integrate renewable energy sources (RES). In the proposed converter, two half-bridge converters are connected in series at the output stage to enhance the voltage gain. Additionally, the balanced voltage multiplier stage is employed at the output to increase the voltage conversion ratio, as well as distribute the voltage stress across semiconductors; hence, switches with smaller on-resistance RDS(on) can be adopted resulting in an improvement in the efficiency. The converter takes advantage of the clamp circuit not only to confine the voltage stress of switches, but also to achieve the soft-switching, which leads to a reduction in the switching loss as well as the cost. The mentioned features make the proposed converter a proper choice for interfacing RES to the DC-link bus of the inverter. The operation modes, steady-state analysis, and design consideration of the proposed topology have been demonstrated in the paper. A 1-kW laboratory prototype was built using gallium nitride (GaN) transistors and silicon carbide (SiC) diodes to confirm the effectiveness of the proposed topology.
