<p>electrical accumulator unit includes a power storage device 26, a first switch 28, a power converter 30, a controller 34, and a dissipation circuit 36 for dissipating energy remnant in the power converter when the electrical accumulator unit is turned Off. The first switch connects the power device to the power converter, which includes at least a second switch that is selectively turned On and Off to regulate the transfer of power between the power storage device and an output of the electrical accumulator unit. The controller turns Off the electrical accumulator device by turning Off the first switch, thereby disconnecting the power storage device from the power converter, and turning On the second switch to connect the dissipation circuit to the power converter in a recirculation circuit path that dissipates energy stored in the power converter.</p> |
