FN660071 Working Principle

The FN660071 oscillator is based on a full-bridge topology. Two power transistors are connected to the output terminals of the oscillator in a full-bridge configuration. As the power transistor switches between switches it alternates current between high and low levels. This alternating current is further tuned to create the desired frequency range by using an amplifier and a low-pass filter.

The oscillator uses two power transistors to create an alternating current and also to control the frequency. When the electric current reaches the transistor pair, the two transistors conduct and the current is switched between them. As the transistors switch, the current alternates between high and low levels, generating the oscillator’s output frequency. The frequency can be adjusted by changing the signal voltage.

The output of the oscillator can also be tuned or manipulated by adding an appropriate amplifier and a low pass filter to the circuit. The amplifier is used to amplify the signal and the filter is used to remove any higher frequencies from the signal. This allows for a better control over the output frequency and its stability.
