Hello,
Please see attached image. The goal of this project is to achieve roughly 64 volts or more from a 12volt battery.
First start with 12volt battery powering L298 board. This is an Hbridge module that powers an arduino board also. The arduino connects pins 12 &13 to inputs 1 and 2 of the Hbridge. It is then coded to generate a pulse on each pin similar to a 60hz pulse. Here is code :
void loop() {
digitalWrite(MOSFET1, HIGH); // MOSFET1 on
delayMicroseconds(360);
delay(8); // wait for 8.3 mS
digitalWrite(MOSFET1, LOW); // MOSFET1 off
digitalWrite(MOSFET2, HIGH); // MOSFET2 on
delayMicroseconds(360);
delay(8); // wait for 8.3 mS
digitalWrite(MOSFET2, LOW); // MOSFET2 off }
The output of the hbridge gives steady 12vac. This is then fed to the secondary leads of a 18v transformer(110v primary/18v secondary). The output on the primary is stepped up to roughly 57v then rectified and filtered using the circuit provided in the attached image. The DC output is a steady 64.2vdc but Im concerned about the AC voltage I also measure on the output. When I switch the multimeter to AC, the voltage is doubled or more.
Why am I seeing this ac voltage?
