  • Summary:
    A small Czech company has invented an inductive heating circuit, which is an innovative simple device intended to ensure high efficient inductive heating of boilers up to 1000°C by using electrical energy of photovoltaic panels, batteries or wind power plants. The system solve hot water management and energy storage. The company is looking for partners dealing with photovoltaic installations that can use the invention in houses based on commercial agreement with technical assistance.
  • Description:
    In the present time heating of water is carried out for example by boilers which are using gas, solid fuel, oil or petrol. The most popular boilers are electrical boilers combined with photovoltaic panels, which produces direct electrical current. Water is heated by the current flows through a heating electrical energy to heat energy intended to heat water or to heat another warm conductive heating medium, for example transformer oil, not freezing fluid and so on.
    Because power output of the heating systems with photovoltaic panels depends on sun shine, even small decrease of the sun light influences quality of the heating process. It is very important to ensure the highest heating effectivity, respectively the highest power output of heating elements, even for cloudy days.
    The aim of the invention offered by the small Czech company is to present a heating circuit, which removes above mentioned disadvantages of the-state-of-the-art and ensures high effective heating.
    The above mentioned disadvantages - and also in comparison with the competing solutions - are considerably eliminated by induction heating circuit comprising a positive input terminal, a negative input terminal, an induction heating coil, where primary source of direct voltage energy is connected to the positive input terminal and to the negative input terminal, where the positive input terminal is connected to an inputs of two coils. The output of the first inductive coil is connected to the cathode of first zener diode, to the cathode of first transistor, to the output terminal of a capacitor battery and to the output of the inductive coil, the output of the second inductive coil is connected to the cathode of second zener diode, to the cathode of the second transistor, to the output of the capacitor battery and to the output of the induction coil, the emitter of the first transistor and the emitter af the second transistor are earthed and connected to the negative input terminal, the output of the first resistor and the output of the second resistor are connected to the control terminal.
    The cooperation offered will be based on commercial agreement with technical assistance. The company will deliver the offered solution to the partners installing photovoltaic power plants or domestic water heating systems for further utilization.

  • Advantages and Innovations:
    Efficiency of an inductive heating systems is higher than efficiency of a system which use heating resistant coil, even if electricity of common power network is used. High efficiency of the presented system according to the invention is not ensured by use of expensive common alternating energy but by us of ecological clean energy produced by photovoltaic paness or by wind power plants or another renewable source of electrical energy, so by usage of direct current. Efficiency of the presented inductive heating circuit according to the invention is from 83% to 94%. Heating speed is faster by 50%.
    The inductive heating circuit according to the present invention is cheaper, because only half of power output is used in comparison with heating systems of the state of the art.
