Embodiment Construction

[0049] figure 1 A reduced schematic circuit diagram of a high-frequency generator 10 is shown, which comprises a magnetron 48 which is connected via a line 50 to the high-voltage generator 12 . The high-voltage generator 12 is supplied with electrical energy by a charging unit 42 which is connected for this purpose to a public energy supply network (not shown in further detail) and is supplied with electrical energy therefrom. In the present case, the charging unit 42 is designed to be supplied with a three-phase alternating voltage of approximately 400 V via the public energy supply network. Furthermore, the charging unit 42 is designed to supply a power of approximately 10 kW. The charging unit 42 provides a charging DC voltage of approximately 400V. The magnetron 48 and the electrical line 50 form an electrical circuit 46 .

[0050] High voltage generator 12 provides high voltage pulse 14 ( image 3 ), the high-voltage pulse is applied to the magnetron 48, so that the m...

Abstract

The invention relates to a high-voltage generator (12) for providing high-voltage pulse (14). The high-voltage generator includes a plurality of energy storage cells (16,18), each including two inputand two output terminals (20,22,24,26) and a capacitor (28). A controllable switching element (30) is connected to the input terminals (20,22) and plus terminals (20,24) and minus terminals (22,26) are electrically connected to one another via a respective diode. The high-voltage generator further includes a series connection comprising the energy storage cells (16,18), a pulse transformer (36), and a charging terminal for charging the capacitors (28). In an embodiment, the high-voltage generator is developed so that a greater pulse rate can be achieved. In an embodiment, at least a respectiveone of the energy storage cells (18) includes an electrical resistance (44), connected in series with the diode connecting the plus terminals (20,24) of the respective energy storage cell (18).
