I am working on a new project, and I need to build a big PCB with a lot of circuits integrated. Therefore, I need to make a power supply on the PCB.
Since I am not comfortable with SMPS design, I decided to make a linear power supply with a series regulator. I am still designing the circuit in simulation (Multisim). The other day I was measuring currents on the secondary side, and noticed the RMS current of the transformer and bridge rectifier is greater than the load current.
So far as my knowledge goes, the transformer and bridge rectifier need to handle the almost 2 A of RMS current I am getting, but the load is only around 700 mA.
How is this possible? Am I doing something wrong?
