Abstract: Various aspects of the present disclosure are directed to energy accumulator emulators. In one embodiment, an energy accumulator emulator is disclosed including a DC-to-DC converter having a number of power switches, a control unit that calculates a reference current from electrical variables of the DC-to-DC converter, and a battery model connected to the control unit. The battery model receives and processes the reference current and communicates a referenced voltage to the control unit. The control unit includes a voltage controller that processes the reference voltage and controls a current, on the basis of which the control unit controls the power switches via switching pulses to control an output voltage. The energy accumulator emulator further includes a PPPC unit that is connected to the voltage controller. The PPPC unit provides a number of pulse patterns, selects a pulse pattern, and controls the power switches according to the selected pulse pattern.

Abstract: The invention describes a method for transforming a liquid (8) into a gaseous state for a cutting process with a water-steam cutting device (1), consisting of a torch (6), an evaporator (25), an energy supply and a supply line (31) for a liquid (8), an appropriate temperature (27) being generated for evaporation of the liquid (8). To create a method of this type it is now provided that the temperature (27) is regulated during operation such that a sensor (28) senses the temperature (27) of the evaporator (25) and transmits it to a regulation unit which correspondingly supplies a heating element (24) with the energy necessary and by which a required pressure (34) of the liquid (8) supplied to the torch (6) is regulated so that an approximately constant temperature (27) of the evaporated liquid (8) is provided for a cutting process.
