Working principle of 550SA220M000DG force oscillator

The working principle of 550SA220M000DG force oscillator is based on the combination of current feedback circuit and impedance matching transformer.When the signal is applied to the primary winding of the transformer, it generates a large magnetic field, and then the current through the transformer will cause the magnetic field to change, thus producing the secondary winding voltage.

The voltage induced in the secondary winding passes through the transformer and is used to control the current that flows through the power amplifier. When the resonance frequency of the oscillator circuit is matched, the signal passing through the power amplifier will be amplified. After the restricted amplification and Voltage cycle conversion, the output signal of the oscillator circuit will become larger, and finally the alternating current of different frequencies will be output.

In addition, the voltage is also sent back to the input end to form a positive feedback loop. This forces the power amplifier to increase the amplitude of the signal, thereby enhancing the performance of the oscillator. This is the working principle of the 550SA220M000DG oscillator.
