My question is this: When it comes to replacing caps, you can go to a higher voltage rated cap but have to stick to the same farad rating? The bad caps are both 6.3 V, 4700 µF and i was thinking of replacing them with 16 V, 4700 µF but getting the better quality 105 °C rated one as the others ones are 85 °C rated.

On some power supply front-ends (AC/DC conversion) with a voltage doubler the capacitors are in parallel at low voltage and in series at high voltage. This works out well since for a constant power out the current is double at the lower voltage. If you series-connect two equal value capacitors in series, cathode-to-cathode and use only the

The location of low-voltage capacitors in an installation can either be central (one location for the entire installation), by sector (section-by-section), at load level, or a combination of the latter two. Installing capacitors allows voltage drops to be reduced upstream of the point where the PFC device is connected, therefore preventing

The problem is that you can not connect an ideal voltage source of a given voltage in parallel with an ideal capacitor that has some initial voltage different from the source voltage. Once these two are connected, our definitions of "ideal voltage source" and "in parallel" demand that the voltage across the capacitor instantaneously changes.

Of course, for conventional electrolytic capacitors, it is simply more cost effective to use a capacitor with a higher voltage rating, or a bunch of high voltage lower value capacitors in parallel. At a simpler level, for low duty cycle / low load applications, a passive balancing approach can be adopted.
Operating a high voltage capacitor at lower dc voltage cause some low continuous current to flow through the capacitor, thus rendering the capacitor not behaving ideally as a capacitor. The voltage rating of the capacitor is the point at which the dielectric & insulation between the two plates starts to break down and fails.
For a capacitor, one of the limits is keeping the voltage low enough that the capacitor dielectric stays intact. As you increase the terminal voltage, the electric stress increases across the dielectric, and eventually, it breaks down. When that happens, you don't have a capacitor any more.
You tend to find more like the opposite. A high voltage capacitor will have it's capacitance rated at low voltage meaning when operated close to it's rated voltage the capacitance will be much lower. This is why the different MLCC capacitor dielectric types exist, they guarantee a certain capacitance vs voltage characteristic (amongst other things)
Installing capacitors in electrical systems fulfils several functions. Although the most well-known is power factor compensation, they also improve the voltage regulation of transmission lines by reducing the voltage drop and increase the capacitive component of lines that are naturally inductive.
Selection of the voltage dropping capacitor for capacitive power supply, some technical knowledge, and practical experience requires to get the desired voltage and current output. An ordinary capacitor will not do the same job since the mains spikes will make holes in the dielectric, and the capacitor will fail to work.
