Piezoelectric actuators typically need to be driven by high voltage (on the order of 50V to V) to produce the desired amount of force or displacement. There are several methods to generate this voltage, and it is important to select one that suits your www.doorway.rug: pzt. · A piezo amplifier driver is commonly used for direct driving of high-frequency and high-capacitance transducers such as actuators, buzzers, motors, etc. PZT transducers and motors are very capacitive in nature. If the frequency is high, their impedance is low due to their large www.doorway.ruted Reading Time: 8 mins. Our high power piezo transducer driver are able to output high current and high voltage, thus high power. To further increase the piezo driver amplifier output power/current, 2 or three or more units may be parallel connected. To do so, each PZT transducer driver is isolated from one other with a series resistor as shown in Figure 3.
Figure 6 is an example of converting a bipolar amplifier into a unipolar high voltage for a piezo device while driving high current and high power at the same time at high frequency. The PZT element has a capacitance of 1 uF. It requires a peak voltage of 80V (0 to 80V sinewave). The desired sine voltage frequency is 11 kHz. The piezo amplifier output voltage is from V to +40V. Because the amp driver voltage is not meeting the required 80V, a DC bias power supply is used as shown in Figure 6. hartytp changed the title [RFC] new EEM: zapper [RFC] new EEM: zapper (high-voltage source/PZT driver) . Copy link hartytp commented . Use Resonance with a High-Voltage Piezo Driver. By exploiting a PZT’s impedance, this series-resonant technique basically transforms a high-current piezo amplifier into a high-voltage.
Piezo drivers specifically designed to drive piezo devices with high stability. High speed operation of Compact module type high voltage power supply. Sept A piezo amplifier driver is commonly used for direct driving of high-frequency and high-capacitance transducers such as actuators, buzzers.
