    less partially by the main power supply module. The secondary current supply module is operable at least in the heating operating state by the main current supply module, as a consequence of the voltage at least partially influenced by the main current supply module and applied to the supply module secondary current, dependently on and exclusively together with the main current supply module. The term "rectifier unit" includes the concept of a unit that is intended to rectify an applied alternating voltage, in particular, each half-wave of an applied alternating voltage, and to supply the rectified alternating voltage as a direct voltage for the main supply module of stream. An alternating voltage is applied to the rectifier unit which is configured as a mains voltage and, advantageously, is supplied by a voltage source of the cooking appliance device. The continuous voltage rectified by the rectifier unit has a frequency that has a value that is twice the alternating voltage applied to the rectifier unit. A ripple of the rectified continuous voltage by the rectifier unit has twice the frequency of the alternating voltage applied to the rectifier unit. The rectifier unit is independent of the power supply modules, in particular, the main power supply module and the secondary power supply module, and is made separately from the power supply modules. The rectifier unit could be made as a complete bridge rectifier and / or as a three-phase rectifier and / or as a rectifier and / or as a bridge rectifier and / or as a half-wave rectifier. The rectifier unit is made differently with respect to a single phase rectifier, and differs from a single phase rectifier. The rectifier unit has four rectifier diodes, namely, a first, a second, a third, and a fourth rectifier diode. The rectifier diodes are provided to jointly rectify the alternating voltage. The first and second rectifier diodes are arranged in a serial connection. The third and fourth rectifier diodes are arranged in a serial connection. The serial connection of the first and second rectifier diodes and the serial connection of the third and fourth rectifier diodes are arranged in a complete bridge connection and connected to each other through a bridge branch, in which a source is arranged voltage of the cooking appliance device. The cooking device has at least one voltage source that is configured as an alternating voltage source. The voltage source could be connected to an electrical network of a cooking appliance and / or be formed by an electrical network of a cooking appliance. The term “planned” includes the concept of programmed,

    connecting element and / or as a resistive electrical component. However, the voltage transformer element is preferably made as an inductor. In particular, the voltage transformer element is made as an inductor made differently with respect to a heating inductor, in particular a heating element. By way of example, the voltage transformer element could be any serial connection and / or any parallel connection of inductors. The voltage transforming element is an inductor. In this way, the voltage supplied by the grinding unit in at least one heating operating state can be optimally adapted and / or modified.
    In addition, it is proposed that the cooking appliance device has a lifting drive stage, which has the voltage transformer element and at least a part of the main current supply module. The voltage transformer element is particularly advantageously realized as an enhancer inductor. The lifting drive stage is intended to transform an input voltage into an output voltage that is higher than the input voltage. The term "lifting drive stage" includes the concept of a voltage driving stage that is intended to transform a first voltage, namely, the input voltage, into a second voltage, specifically, the output voltage. The lifting actuator stage presents the voltage transformer element realized as an inductor, in particular as an enhancer inductor, a diode connected in series with the voltage transformer element, a connection element, and a capacity, in particular, a capacity of filtering, which is arranged at one end, opposite the voltage transformer element, of the series connection of the voltage transformer element and the diode. The control unit is intended to apply the input voltage to the voltage transformer element by modifying the connection position of the connection element of the lifting actuator stage, and to connect the voltage transformer element and capacity in parallel to each other. The voltage transformer element is intended to increase the energy stored in the voltage transformer element in the event that a connecting element of the lifting drive stage is closed, in particular, with an input voltage being applied. Likewise, in the event that a connection element of the lifting drive stage is open, in particular, without an input voltage being applied, the voltage transformer element is provided to maintain without modifying the current flow that flows to

    It is possible to increase the efficiency to a greater extent by means of a method for putting into operation a cooking appliance device according to the invention, in particular, a cooking field device according to the invention and, advantageously, a cooking device Induction cooking field according to the invention, with a main current supply module, which is intended to supply at least one heating current, and with at least one secondary current supply module, which is intended to supply at least one other heating current, where at least one continuous voltage is supplied to the main current supply module.
