The regulator system have a sophisticated ripple filtering solution using selectively distributed multi-band capacitors. The control circuits themselves are additionally improved by a low-pass filter on the power supply. Thanks to this, the supply of the control circuit itself is separated from possible high-speed voltage drops on the main branch of the source. Thanks to its sophisticated design, the regulator itself is very precise, temperature stable and does not suffer from ripples and high noise. The regulators are galvanically separated from each other, so it is possible to power each regulator with its own source at different potentials. However, this functionality can be easily excluded from the function using jumpers, which allow each potential of each regulator to be connected to a shared power branch, which again increases the variability of use. We managed the design of the PCB itself on a two-layer PCB, and despite the very densely stacked components, we managed to distribute the power supply and ground with very robust routing. Thanks to the flat design on the aluminum core, we met the requirement for heat dissipation using the chassis.

The request from NenoVision was to use a computer-controlled ADC to selectively heat the parts in the specified places in the microscope, which we managed well thanks to our solution. In addition, thanks to the multi-channel solution, our system also serves as a stable source of some other systems.
