Hi, I need a high voltage circuit designed. I need to be able to transform a low voltage (ideally between 12-24V) to a very high voltage of 45,000V, so there is a potential difference between two electrodes 45,000V (i can then vary the electrode size, distance to create the desired electric field strength etc). The output voltage needs to be variable to a minimum of the low input voltage and to a maximum of 45,000V.

We have a small board based on PIC18F14K50 that is currently used for GPIO. We need a different firmware to support PWM and SPI. The board has a USB (Virtual com port) for communication with PC. PWM and SPI should be controlled via com port commands. PWM - 2 channels, programmed: frequency, duty cycle and on/off SPI 4channels - programmed:channel, payload (bytes to send). We will provide the board, description/schematic and Virtual com driver for development.
