Currently i am doing a circuit for achieving voltage regulation. Please refer below for the same.
I am looking for a split voltage supply design using a single supply.
On No-Load i am getting the split supply across the zener and the remaining voltage across the resistor.
The Load will not be present simultaneously as i am using this supply for IGBT ON/OFF. So the voltage split is bizarre when individual loads are removed or connected.
I understand that there are IC's for performing this function of creating a dual voltage from single supply, but i am looking a cost effective one. This is one reason i went with this conventional way .
Please suggest me a way to solve this problem.
Thanks in advance.
