Abstract
Electrical apparatus to kill a plant or at least attenuate plant growth, the apparatus comprising: an electrical energy supply unit; a applicator unit comprising an applicator electrode; a return unit comprising a return electrode; the electrical energy supply unit arranged to apply electrical energy through a transmission circuit comprising the applicator electrode, and the return electrode, the electrical energy supply unit including a plurality of transformers, each transformer having a low voltage side and a high voltage side, wherein the high voltage sides of the transformers are electrically connected to implement transmission circuit, and/or the low voltage sides of the transformers are electrically connected.
Claims25
A system to electrically kill a plant or at least attenuate plant growth, the system comprising:
- a plurality of modules, each module comprising:
- one or more pairs of an applicator electrode and a return electrode, and;
- module electrical circuitry to control a waveform shaping system to control a waveform in electrical energy applied through a transmission circuit comprising the applicator electrode and the return electrode of said pairs, the modules arranged to receive electrical energy from a power supply, and;
- master electrical circuitry is configured to control the module electrical circuitry to apply the electrical energy for each module in a synchronised manner relative to the other modules.
A method of controlling electrical energy of a system to electrically kill a plant or at least attenuate plant growth, the method comprising:
- controlling via master electrical circuitry and module electrical circuitry, an electrical energy output of a plurality of separate modules to output said electrical energy in a synchronised manner,
- wherein said modules comprise the module electrical circuitry to control a waveform of the electrical energy and an applicator electrode and a return electrode.
