  "textContent": "The piezoelectric actuator control system for fuel injector valves for an internal combustion engine has a charging and discharging circuit (6). This circuit has separate charging (S2) and discharging (S3) switches in parallel with diodes (D2,D3) and a transformer (3). A 12v power supply is connected to a transformer (2) and the primary (W1) of the switching transformer is connected in series with the charging switch and diode with a resistor (R2). The secondary (W2) of the switching transformer is connected in series with the discharging switch and diode with a resistor (R3). The charging and discharging circuit is connected to an ASIC (Application- Specific Integrated Circuit 8). The switching circuit is connected to an actuator (CP) in series with a selection switch (1) and a resistor (R1).",
