In the realm of electronics, the need for oscillators that can be adjusted is of paramount importance, especially in applications related to DC to DC conversion. The creation of a Voltage Controlled Oscillator (VCO) that utilizes the NE555 and is controlled by the ATmega328 microcontroller is a significant development in this field. This innovative tool is designed to function as a frequency and controlling pulse width (PWM) generator with an output frequency reaching 65 KHz.

Description of the Tools and Their Functions

The VCO tool is a combination of Arduino and NE555, which work together in converting digital signals into analog signals. The Arduino microcontroller acts as a controller, sending PWM signals to the VCO. This microcontroller is capable of adjusting the frequency value and width of the pulse, which is then sent to the Digital-to-Analog Converter (DAC) to convert digital values into analog signals. The output of this oscillator can be utilized in various laboratory experiments, such as the conversion of voltage with the ability to increase (boost) and decrease (buck) voltage.

Tool Work Principle

This system is associated with a voltage source from PLN through an adapter. After the system is activated, the microcontroller will store the required data to adjust the desired frequency and pulse width. The DAC will then directly function to convert digital signals into analog signals. The resulting analog value is then sent to the NE555 oscillator, which acts as a frequency generator.

The resulting frequency, which is 65 KHz, is sent to the FET IR2110 driver, which will strengthen the signal to produce a stable frequency output. The output signal of the Ne555 is in the form of a rectangular wave that changes between high and low levels at a certain time. With these characteristics, this oscillator has great potential to be used as an efficient high voltage generator.
