A power electronics module includes a capacitor having a trough-shaped housing and at least one capacitor winding. An electronic unit includes a base on which the capacitor is mounted. A cooling plate in thermal contact with a cooling surface of the capacitor is formed by a bus bar. The cooling plate is on the base of the electronic unit.

Disclosed is a LADAR system and a method for operating same. The LADAR system includes circuitry for generating the electrical signal with an optical signal detector using N discrete samples; a bank of M parallel sample/hold circuit unit cells individual ones of which operate with an associated sample/hold clock, where each sample/hold clock is shifted in time by a fixed or programmable amount Δt relative to a sample/hold clock of an adjacent sample/hold circuit unit cell; and further includes circuitry for sequentially coupling a sampled value of the electrical signal from a first output of individual ones of at least some of the M parallel sample/hold circuit unit cells to an analog to digital converter circuit. Each of the M parallel sample/hold circuit unit cells has a second output for outputting a digital signal for indicating the state (low or high) during a time that the associated sample/hold clock allowing for time of arrival determination. The LADAR system further includes or is coupled to a signal processor for deriving an image of the object and a range to the object based on signals at the first and second outputs. Assuming an effective sample/hold circuit sampling rate of X samples per second, a sampling rate of each of the M parallel sample/hold circuit unit cells can be X/M samples per second.
