Dave shows you how to design a simple constant current and constant voltage lab power supply that can be either software (PIC/AVR et.al microcontroller) or traditional pot controlled. Special challenge in the high voltage equipment design relates to a trade-off between the device sizes and levels of the electrical stress in the insulation.Smaller distances and sharper edges between high-voltage(HV) and grounded electrodes cause higher electrical stresses, which may result in higher rate of insulation aging or even the electrical breakdown.
