The apparatus comprises AC generating means for generating a substantially sinusoidal alternating current (AC) drive current and DC generating means for generating a direct current (DC) bias current.

The current divider can generate a divided current by dividing an input current by an adjustable division ratio.

The trailer box refrigeration system may have either a generator for generating direct current (DC), or an alternator for generating alternating current (ac).

The invention relates to a generator for vehicles for generating electric current.

The power supply is arranged to generate a pulse current.

Other particles can pass through the sample entirely and generate a current that can be measured.

The output circuit serves for generating an output current.

A brush metal switch for generating a pulse current.

Furthermore, a fan wheel is provided in order to produce a stream of cooling air.

The charging current is indirectly sensed to generate a sensing current having a predetermined relation to the charging current.

The power source is able and adapted to generate a modulated current The gas inlet is coupled to gas supply means (25,26) which are able and adapted to admit the gas to be excited at a modulated, sub- atmospheric to above-atmospheric inlet pressure.

The electronic circuit (100) also includes a bias current generator (124) for generating a bias current.

The current regulator is configured to generate a current, and the inductor is configured to store energy generated by the current produced by the current regulator.

MP-D machines may be powered or may generate direct current.
