with dummy resistive load i have output 21Vrms @ 36VDC but with transformer connected i have 0vac, regulatior TL783c regulates my 36V to about 22v @700ma then to casacded booster(TIP41C,42C) then to 7812 (12v regulator ) then to (7805) 5v regulator for arduino
my current boost transistor for my...
I have removed the capacitor n still get low voltage at my highside driver outputs. Could u redraw my schematics may b my connection of the high side is wrong but low side seems OK . highside is at spwm frequency of 16kHz,low side is at 50Hz
Could it b an error in my connection of the high side because my low side seems ok with 10.4-11.2vat low side but at high side í still get a low voltage 6.7Vac to 7.8Vac . I am using veroboard to test could u show me the connection by redrawing the schematic please!
My pwm frequency is 16kHz. I have removed the second driver using tip 41&42 transistors but yet I still get 6.8-7.8VAC at my high side outputs but at my low sides I get BTW 10.4-11.2VAC which seems OK . by the way I am prototyping on veroboard .
Irfb4110 has gate charge of 210nC max and rise time of 67nS shouldn't my gate current be 210/67 = 3.13A. And my tlp250 can only source .5A and sink 1.5A .
