A discontinuous conduction current mode maximum power limitation photovoltaic converter connects to a ground and a solar cell having a temperature compensation signal and an output power and being solarized and includes a direct currentdirect current voltage converter and a maximum power control circuit. The horizontal machine tool is adapted such that a workpiece supporting member is installed on the base part in front of the saddle supporting part. The present invention may be part of the commissioning of a new or old pipeline or a new portion of a pipeline in which a purging of the line with a compressed gas and drying of the line is required. A plurality of electrically conductive contact areas are disposed within the slot.
