Testing power supply
Under what conditions, power supplies are tested, and are considered qualified?(every kind of power supply )
For example if power supply is rated at 5v300mA , if it has a transformer, it means when there is a 300 mA load, you should have 5v across the PSU? while it might have 8v under no load, and if it's switching its always 5v until max 300mA is reached?
I came across some circuit which was pretty odd to me (the design style) I was wondering if this was a safe design and will always result in the same voltage over same provided input or not.
My whole idea was to use same approach by using a pwm ... to make a variable psu.
