What component is responsible for increasing frequency in high frequency treatments?

In high-frequency treatments, the component that plays a crucial role in increasing frequency is the oscillator. An oscillator is a device that generates a repetitive waveform, typically a sine or square wave, which is essential in high-frequency applications. In the context of high-frequency electrolysis, the oscillator sets the frequency at which treatment is performed, allowing for effective hair removal.

While the amplifier enhances the strength of the signal, and transformers can adjust voltage levels, neither is primarily responsible for generating or increasing frequency. Transistors also may be involved in electronic switching or amplification but do not specifically create frequency changes like an oscillator does. Therefore, the oscillator is the key component for frequency modulation in high-frequency treatments.
