Weed inactivation device

A weed inactivation device, comprising at least two electrodes, whereby at least one electrode is directed to a weed, wherein, the at least one electrode is supplied with electrical energy by at least one electrical power supply, the electrical power supply comprising:

• at least one electronic h-bridge inverter for DC/AC conversion, creating a rectangular wave AC-current, the pulses at the electronic h-bridge inverter being controlled such that the overall current of a control system of the weed inactivation device is controlled;
• whereby the DC/AC conversion takes place at frequencies above 1.0 kHz;
• at least one transistor connected to the control system that is further configured for providing a pulse density modulation (PDM), and
• a parallel current controlled transformer system comprising a plurality of individual transformers,
• wherein the at least one electronic h-bridge inverter connected to the control system that is further configured for providing a pulse width modulation (PWM), and
• wherein the combination of the individual transformer PDM current control and the electronic h-bridge inverter divides the power between the electrode segments and controls the current at each electrode segment individually with dynamic precision trough the PWM control of the AC of the output of the electronic h-bridge inverter.
