PICAXE based inverter
January 27, 2012
I've been having this idea for awhile. Create a dc to ac inverter using 2 8M PICAXEs as the timer Controling an H-bridge hooked up to a 12VDC battery. Then have the first PICAXE control an H-bridge to convert 12VDC to 12VAC. The MOSFET H-bridge would be sent to a full-wave voltage multiplier circuit, using diodes and capacitors, converting it into around 192VDC. Then this would be the power given to the second MOSFET H-bridge and another set of 4 I/O pins from the second 8M PICAXE would control the H-bridge into converting it into 192 VAC@60Hz.
I have an idea of creating a microcontroller based inverter using the 08PICAXE. The 08PICAXE is simply just the timer to create "synthetic" AC current. The PICAXE controls two MOSFET H-bridges. Each H-bridge has 5 N-channel parralled, another 5 N-channel parralled, 5 P-channel parralled, and another 5 P-channel parralled. The idea is to eliminate the use of a transformer and have maximum wattage with a reasonable price. The first H-bridge is connected to P0, P1, P3, P4 and a 12VDC power source. The PICAXE timer creates a 12VAC@58hz. This is then sent to a diode and capacitor multiplier(10x) circuit. The voltage is now 120VDC. This is sent to the second h-bridge to be converted into 120VAC@58Hz. The second H-bridge is connected to P0, P1, P3, P4 and the voltage multiplier circuit.
Full and Half wave camparison
What do you guys think. I will look forward to your criticism and word of wisdom ;D.
