RF power supply principle is to convert the low frequency power supply electrical energy into high frequency electrical energy, through the role of electromagnetic field to produce high frequency electric field or magnetic field.
RF power supply is a kind of power supply used to generate high-frequency electric field or magnetic field, widely used in wireless communication, medical equipment, industrial heating and other fields. The basic components of the RF power supply include power amplifier, resonant circuit, matching network, control circuit, etc., of which the power amplifier is the core component of the RF power supply and its role is to convert the low-frequency power supply into high-frequency power. The resonant circuit is used to adjust the output frequency to match the desired frequency.
The matching network is used to adjust the output reactance to match the load reactance, thus increasing the output power and efficiency. The control circuit is used to control the operating state of the power amplifier to ensure its stable and reliable operation. When an RF power supply outputs a high-frequency electric or magnetic field, it interacts with the load to produce electromagnetic induction. This electromagnetic induction causes changes in the charge and current in the load, thus producing the desired effect.
RF power supply
RF power supply is a power supply that can generate a fixed-frequency sinusoidal voltage with a frequency in the RF range and a certain power. It has been widely used in semiconductor process equipment, LED and solar photovoltaic industry, plasma generation in scientific experiments, radio frequency induction heating, medical cosmetology, atmospheric pressure plasma sterilization cleaning.
Radio frequency, also known as radio frequency, wireless radio frequency, high frequency, for the oscillation frequency in the range of 3kHz to 300GHz, this frequency is equivalent to the frequency of radio waves, and the frequency of the alternating current carrying radio signals.RF is usually used to refer to the electronic oscillation, and is not used in the mechanical oscillation, however, the mechanical radio frequency system is still there (such as mechanical filters with the RF MEMS).
