Benefits of technology
The patent describes a conversion circuit, system, and method for carrying out an electrochemical process that accelerates the process by providing a higher level of efficiency. This is achieved by using an input stage with a reactive input impedance that confers a substantially higher power uptake than the resistive component. The input stage can be a capacitor or a capacitor bank connected in parallel or series with the supply terminals. The conversion circuit can be connected directly to the mains network, eliminating the need for a separate power source. The system includes a container for an electrolyte solution, and pressure waves generated in the solution improve the transport of charge carriers involved in the electrochemical process. The method is relatively short and can be carried out in a container filled with an electrolyte solution. The use of pressure waves with a frequency range of 20 kHz to 50 kHz provides the highest efficiency.
Problems solved by technology
A disadvantage of this apparatus is that the performance of the electrochemical process that takes place during charging the battery is slow.

Embodiment Construction
[0027] The disclosed system of FIGS. 1A and 1B, comprises a conversion circuit and a vessel 2 filled with water 1 forming a fluid bath. In the fluid bath, an electrolysis device 3 has been placed. The electrolysis device 3 comprises a fluid container 4, with a duality of electrodes 5 therein, which are immersed in an electrolyte solution 6. The electrodes 5 are connected to positive and negative poles 7,8 of the electrolysis device 3.
[0028] The circuit is generally suitable for any type of electrochemical process. The example that is detailed herein concerns electrolysis, for example of a sodium chloride solution to win chlorine. In a preferred embodiment, the system forms part of the drive train of a vehicle. This drive train further comprises a power source for driving the vehicle, which power source uses the product of the electrolysis as a source of energy. The power source may for instance consist of an internal combustion engine or a Stirling-motor running on hydrogen, but al...

Abstract
A conversion circuit for converting an alternating current into a feed current for an electrochemical process is provided with at least one supply terminal for supplying an alternating feed current, a rectifier circuit for rectifying a supplied alternating feed current, and an output stage for supplying the rectified current to a device in which the electrochemical process is taking place. The conversion circuit is further provided with an input stage connected between the supply terminals and rectifier circuit, which input stage, when in use, confers upon the conversion circuit a substantially reactive input impedance.
