Tool/software: TINA-TI or Spice Models
Hi everyone!
I am about to build a 3-phase power source.
I could build one like this:
Or like this:
If i build the first one (my own schematics):
-Do i need the diodes? -should i put them as in the second one?
To get 3 x 230 +/- 10 Volts 50Hz
-how many Ohms should the resistors have?
-how "big" should the capacitors be?
Should the transformers be 12- 0 -12 & 230 Volts? ...or ? -tell me!
If i build the second one:
Should i use a rectifier? ...or a voltage doubler? -do i get as much Voltage i need? -between phases.
C1 -how "big"?
R1 -do i need it? -why? -what for?
Both:
-How do i make the square-wave to a sinus-wave?
I have tried make the wave less square, more like sinus in the first one with th capacitors and the resistor between diodes and transistors.
-Am i doing that right? ...or wrong? -how sould i do?
-How should i do to adjust the output Voltage?
If i know what i need to know and succeed building one of theese i'm going to power a cirulation-pump with it.
The pump consume 83 Watt.
Anything else that i should know? -Tell me!
Thank you very much!
/M.
