Film capacitors: Characteristics and uses in power applications
Film capacitors as power filters. Although filtering is often seen as a signal level function, in inverters and motor drives particularly, output capacitors pass high ripple currents to prevent high dV/dt levels on cabling causing stress and EMI (Figure 7). As AC is passed to the load, the capacitors must be non-polarised, anyway excluding use ...
