What Is a Frequency-To-Voltage Converter?
A frequency-to-voltage converter is a device that converts frequency (Frequency) into voltage (Voltage) in proportion to the speed of rotation or movement.
It is used to monitor and analyze changes in frequency. There is also an inverse converter called a VF converter.
This equipment is also used for motors used in hybrid and electric vehicles, as well as for high-speed production lines in manufacturing plants. It can measure start-up characteristics, minute rotation fluctuations during steady-state rotation, and transient phenomena of flow velocity changes with high-speed response.
Uses of Frequency-To-Voltage Converters
Since frequency is not visible, frequency-to-voltage converters convert frequency into voltage. Since analog signals, which are vulnerable to noise, are not suitable for long-distance movement, they can be recognized as digital values when an AD converter (a device that converts analog signals into digital signals) is used together.
Items that can be checked include motor rise characteristics, rotational performance measurements of various rotating equipment, engine and motor rotational fluctuation measurements, and rotational performance tests due to overloads.
Principle of Frequency-To-Voltage Converters
Passing a pulse signal through a frequency-to-voltage converter creates a signal that decays over time, and the overlap of the signals enables a voltage signal corresponding to the pulse frequency to be obtained. Analog and digital channels are used.
The signal from the sensor creates a gate open/close signal at the comparator. Changing the measurement range switches the reference frequency, and the gate opens and closes according to the period of the input frequency.
What is done during this time is the integration of the number of clocks. At the next cycle, the contents of the counter are sent to the D/A converter, resulting in an output that is converted to an analog signal.
Types of Frequency-To-Voltage Converters
Depending on the type, some devices support multi-channel measurement and small-amplitude signal detectors in rotational speed measurement. Equipped with predictive calculation, smooth output can be obtained even during deceleration, making it useful for acceleration/deceleration and behavior analysis testing of drive units.
A variety of products are available, including those that support high input frequencies and wide input amplifier bandwidths in line with the trend toward rotary encoders with multiple pulses.
Other Information on Frequency-To-Voltage Converters
1. Filtering
Integrated low-pass filtering or programmable filtering is available. Integrated filters pass some signal input frequencies but block others.
The low-pass filter has a set threshold value. Signals below the threshold can pass, while signals above the threshold are blocked.
2. Rapid Deceleration Tracking Function
Some frequency-to-voltage converters have a rapid deceleration tracking function. This function decelerates the rotational output to a stop if there is no input for more than the previous pulse interval when the input signal is suddenly decelerated by a rotating object or the like.
When the follow-up function is ON, the analog output immediately becomes 0 if no signal input is received after waiting for the pulse interval for the set number of times. When the follow-up function is OFF, the analog output becomes 0 after a certain period of time has elapsed after the input signal becomes 0.
3. Trigger Function
When a triggerable voltage pulse signal is input, an F/V conversion output with a one-pulse response proportional to its frequency can be performed. The trigger level is specified by the device and can be set arbitrarily as long as it is within the specified level.
4. Linearity
The frequency-to-voltage converter provides a DC voltage proportional to the frequency, but the wider the frequency range, the lower the linearity between the frequency and the voltage.
This is due to the fact that when the pulse signal frequency is high, a new pulse signal is input before the discharge of the charge stored in the capacitor in the circuit is completed.
Therefore, some frequency-to-voltage converters add a new discharge path to discharge the charge in the capacitor in a short time. Conventional circuits have linearity degradation in the high-frequency bandwidth, but conversion is possible while maintaining linearity.
