A capacitor bank includes first and second spaced opposite polarity DC bus bars and first and second spaced printed circuit boards that extend between the bus bars. A single face of the printed circuit boards includes first and second mutually insulated metal cladding segments. Plural first and second main capacitors have first and second opposite polarity electrodes extending from a single face thereof. The main capacitors, bus bars and plates are positioned and electrically connected to each other so that; the first electrodes of the first capacitors are electrically connected to the first bus bar via the first segment of the first printed circuit board, the second electrodes of the first capacitors are electrically connected to the second bus bar via the second segment of the first printed circuit board, the first electrodes of the second capacitors are electrically connected to the first bus bar via the first segment of the second printed circuit board, and the second electrodes of the second capacitors are electrically connected to the second bus bar via the second segment of the second printed circuit board. Ripple suppression capacitors having a capacitive value considerably less than the capacitive value of the first and second capacitors have terminals connected to the first and second electrodes via the first and second segments. The filter capacitors are positioned so they straddle the dielectric stripe.
