Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional high voltage coil windings are used with multiple layers and turns, then the transformer can handle high voltage and power levels, but arcing between windings occurs which damages the coil and creates unwanted ozone
Solution Approach 1:
The high voltage coil is segmented into multiple independent turns, each formed on a separate substrate. These turns are electrically isolated from each other by insulating substrates, preventing arcing between adjacent windings while still achieving the required voltage transformation ratio.
Solution Approach 2:
Insulating substrates are introduced as intermediary elements between adjacent high voltage turns. These substrates provide electrical isolation and mechanical support, allowing the coil to operate at high voltages without arcing between windings.
2Adaptability or versatility
If the power supply apparatus operates at fixed frequency, then the transformer design is simplified, but it cannot adapt to varying resonance frequencies caused by temperature, pressure, and device changes
Solution Approach 1:
A frequency control system continuously monitors the actual resonance frequency of the ozone generating device and adjusts the operating frequency of the power supply apparatus accordingly. This feedback mechanism ensures optimal operation despite variations in temperature, pressure, or device changes.
Solution Approach 2:
The operating frequency of the transformer is made dynamic rather than fixed. The frequency control system enables the transformer to adapt its operating frequency in real-time to match the varying resonance frequency of the connected ozone generating device.
3Productivity
If only electric power is adjusted to control ozone yield, then the control is simple, but resource consumption including oxygen-containing gas is not optimized
Solution Approach 1:
The system controls multiple operating parameters simultaneously, including electric power and oxygen-containing gas flow rate. By adjusting both parameters in coordination, the system achieves desired ozone yield while optimizing resource consumption and minimizing waste.

AI summary
The invention provides a power supply apparatus for supplying electric power to a capacitive load. The apparatus has a transformer, a positive half-period driver and a negative half-period driver supplying positive and negative half-periods of voltage to the first coil. The second coil forms an electric resonance circuit and supplies electric voltage to the load. Zero crossings of the voltage supplied to the first coil are determined from a third coil on the transformer, and alternation between positive and negative half-periods of voltage supplied to the first coil is done at the zero crossings of the voltage supplied to the first coil.
