This is due to their advantages over bipolar junction transistors (BJTs), which include high-frequency operation and other FETs, such as enhancement and depletion mode operation. Metal-oxide-semiconductor field effect transistors (MOSFETs) are often the preferential transistor type for power conversion applications. However, in the vast majority of cases, regardless of conversion type, transistors are employed.
That includes inversion (conversion from DC to AC), rectification (conversion from AC to DC), frequency conversion (AC to AC conversion), and power conversion (which may be AC to AC or DC to DC). FQP30N06L Mosfet Physical dimensions:įQP30N06L is 3 cm in length and 1 cm wide.One of the most common and yet most required functions in electronic circuitry is conversion. Now, you should be able to control the load current using the FQP30N06L Mosfet.
20 ms delay (can add noticible delay if over 200ms) print out getPotValue to serial monitor set the PWM value on pin 3 for motor speed control the loop routine runs over and over again forever: PotPWMValue = min(potPWMValue, 255) // if above 255 somehow, use 255 max If (potPWMValue < 102)// below PWM value 102(Vgs=2v) use PWM value 0 to avoid rough run Int potPWMValue = map(potAnValue, 0, 1023, 0, 255) // mapping to get 0 to 255 Int potAnValue = analogRead(pot) // read the input pin declare pin 3 and A0 to be an output and input respectively: Int pot = A0 // potentiometer is connected to analog pin 0 Int motorPin = 3 // the pin that the motor is attached to Upload the code given below to your Arduino baord:ĭC Motor speed control using FQP30N06L with Arduino and potentiometer.To know more about Arduino PWM frequency change, read this article. Gate of the Mosfet is connected to the Digital PWM pin 3 of the Arduino UNO here, you can connect it to any other PWM pin according to the Load PWM frequency OR switching frequency requirements.
Load can be a Motor, a lamp, solenoid etc.Connect the Arduino with the Mosfet using the required components as shown in the circuit diagram above.To use FQP30N06L with Arduino follow these steps: FQP30N06L Mosfet with Arduino Circuit Diagram
