Do the math.Using an RC filter with PWM is not really a switch mode regulator.
I hate to see so much false information being spread around.. It confuses everyone.. Especially people just starting out in electronics.
The links you gave earlier were for RC lowpass. An RC lowpass filter on PWM will give -just- as much in losses as a linear regulator.
In SMPS, the series element, RS, is replaced by asemiconductor switch, which offers very low resistanceat the ON state (minimizing conduction loss), and veryhigh resistance at the OFF state (blocking theconduction). A low-pass filter using non-dissipativepassive components such as inductors and capacitorsis placed after the semiconductor switch, to provideconstant DC output voltage.
Read a book, in between insulting me. Perhaps you can show me in one of these documents where a switch mode power supply uses a resistor as part of the smoothing network.
The rectification of the generator AC will distort the generated waveform so badly that is will cause the self excitation to stop.____Paul
With some capacitors connected to the windings, once it gets going, it self-excites and outputs a good amount of power without any issues. I'm
IMAG do not like capacitive loads as Rockwallaby has discovered
It is the forward conduction of the rectifier that causes the colapses the excitation flux, as the current at this point is relatively high and it is being effectively shorted out.____Paul
i just wanted to understand mosfet datasheets...
