Abstract
A controller, for a battery-operated vehicle or the like, comprises a plurality of mosfet/diode/capacitor circuits. A printed circuit board (PCB) has the mosfet/diode/capacitor circuits arranged in four sets, one set along each side of the board, and with the inner areas of the board on both sides and the outer area on at least one side being substantially solid tracking areas forming the connections to the circuits. The connectors (A, B+, B−) to circuits are located substantially along a diagonal of the board, with the connectors (A and B+) to the two sides of the diodes located at opposite corners of the inner areas of the board. The inner tracking areas are divided by isolating lines into separate fingers for the respective circuits. The mosfet and diode of each circuit are mounted on one side of the board and the capacitor on the other, with a heat sink bar located between the mosfet and diode with the mosfet and diode clamped to it by a nut and bolt passing through lugs on the mosfet and diode each a matching hole in the bar.
