    how can I determine the Resistanc and capacitance value in a snubber circuit

    Hi, In the below circuit I would like to know how to determine the the resistance(R9) and capacitance(C6) value ? This circuit is a IOT based fan controller. Here we are using 240VAC, Even though they have shown the values I am interested in knowing how to design a RC snubber circuit for a fan...

    Buck Converter from 48V to 5V

    I am using Arduino and Controlling FAN which works on 48v. so i am using 2 power supply smps in my design. One for Arduino that 5V smps and another for FAN that is 48V smps. I want to use single power supply in my design that is of 48Vdc. I was looking for a buck converter that will take 48V as...

    voltage Stability factor of voltage regulation circuits

    Here a shunt voltage regulator circuit with two zener diodes One zener diode Z give the reference voltage at the comparator for the feedback signal . But I can't explain the role of the second zener diode Z1 I've to calculate Voltage Stability factor (Sv) . Any Suggestion is welcome.

    DC Switching linear regular design question

    Hello, I am fairly new to electronics design (I have a mech e background), and am designing a board that requires dropping 12v to 5v with a large current requirement (up to 8A@5V). In a bid to save on BOM, I took a shot at creating my own design vs buying one off the shelf, using the...

    How to display various parameters (voltage, current and temperature) on 7-segment display every 5 seconds

    I have built an op-amp series pass voltage regulator, whose output is inputted into an analog-to-digital converter (ADC0804). The ADC's output is connected to a CoolRunner II CPLD Starter Board. This output corresponds to a value on a look-up table, which determines what value would be displayed...
