Published:2011/7/17 19:13:00 Author:Lucas | Keyword: Electronic locust killer | From:SeekIC

The electronic locust killer device is composed of the power supply circuit, self-excited oscillator and high-voltage generating circuit, and the cirucuit is shown in Figure 3-191. Power supply circuit consists of resistor R2, step-down capacitor C5, rectifier diode VD5, voltage regulator diode VS and filter capacitor C6. The self-excited oscillator circuit is composed of the time-base integrated circuit IC and potentiometers RPI, RP2, diodes VD6-VD8, capacitors C7, C8. High-voltage generating circuit consists of resistor Rl, doubler rectifier circuit composed of capacitors Cl-C4 and rectifier diodes VDl-VD4, and plate electrode. Rl and R2 select 1/2W metal film resistors. RPl and RP2 use the sealed miniature potentiometers or variable resistors.
