4.1.2.3 Bus capacitance
The bus capacitance consists of all capacitances on a DC link:
DC bus capacitance = power supply capacitance + drives capacitances + other capacitances
An insufficient capacitance will reflect ripples on the DC link that can provide unwanted harmonics which
result in more faults. Capacitors can absorb the regenerated power. By using sufficient capacity, the power
consumption will be reduced. In addition to coping with ripples on the DC bus, the capacitor can also absorb
