Electronic vibrator
摘要:
An electronic vibrator comprises a power source unit converting AC power into DC power, a bridge circuit comprising an insulated-gate bipolar transistor (IGBT) as a power switching device for driving a large-capacity oscillator, a circuit driving unit driving the bridge circuit and applying a sine wave which is a sine wave PWM modulation reference wave as well as a triangular wave, and a vibration generator connected to the bridge circuit, generating vibration by a current supplied by the bridge circuit.
