You have to store the energy in magnetic field somewhere. When I connected a 300 watt load the voltage dropped about 20 volts. The transformer isn't the inductor except for some small leakage inductance, which is minimized. Without feedback there is no noisy sound and the SMPS works fine. Connected to mains or not.ģ- What power inductor you are talking about exactly? if you mean ETD49, It ok Also NO manufacturer allows the customer to touch the guts of the circuit with lethal voltage across.

1- MUR460 is not installed in real SMPS, it was there JUST in case some one used an IGBT without diode.Ģ- 18K resistors in your mind are needed, but I think they are VERY important to bleed caacitors when you disconnect the mains, better than getting shocked by the lethal charge into the capacitor.
