Abstract

Aiming at the needs in field of oil extraction operations, a high-power ultrasonic power supply was developed, and it can generate the power of 55kW and automatically match the inductance. TL494CN is utilized to produce square signal and realize the continuous adjustment within range of 15 kHz ~ 40 kHz with dead time for 3 microseconds. Produce modulation signal via NE555P to form square wave with interval, and modulate the signal produced by TL494CN as final control signal of the power supply. Automatic matching of inductance is realized via circuit composed by HEF4011BP, TC4013BP and direct current (DC) electromotor. Through field test, this ultrasonic power supply can realize the excitation of the highpower and meet its excitation requirements.
