How to convert high DC voltage into AC?
I need to convert high DC voltage to AC at certain freq. how this could be done?
I tested it with a transistor so that feeding the gate with the ac signal frequency and putting the high DC voltage to the drain but didn’t work. any suggestions?
High DC voltage = 100v
Frequency = variable (30k – 50kHz)
Signal type = square wave
AC signal output = 100v square wave
I’ll tell the idea to let you think with me. For my project, i need a square wave signal with frequency range (30k – 50kHz) and with amplitude values (low = 0 & high = 100).
For me to achieve this, i used a 555 to generate the square wave signal with intended frequency. The 555 output signal is (V=7.5v peak) & (I= 35mA). Then i needed to reach to 100v peak. I thought that i may use many stages of voltage doubler (will generate high(100v) but DC). Then i thought i may use a transistor and feed that high DC to the collector and the 555 output to the gate so that get the intended frequency out of the DC signal. Also i searched for transformers to achieve that but i failed. Any suggestion?
