3.2.3  Filter

The filter is designed to filter out the high frequency switching voltage-spikes. It is not intended to smooth the 50Hz ripple at a load of 1kW or more. A capacitor therefore would be too expensive and is not necessary. The main filtering is performed by two high-frequency 5mF capacitors (Arcotronics, Type: MKP C4G, U_n = 700V=) on the rectifying board (Figure 2.1, a). In addition, on each H ‑ Bridge channel PCB a suppressor MKP capacitor is mounted (Figure 3.16, a).
