| Summary: | This paper describes the design and construction of a dielectric barrier discharge (DBD) ozonizer using the single switch resonant converter (SSRC), in conjunction with a piezoelectric transformer (PT). The main advantages of the proposed topology are minimum parts count, small footprint the high efficiency. Furthermore, the chamber uses dielectric made from muscovite mica, which is easy to construct and allows for a low initiation voltage. An experimental prototype of the ozonizer is built; it is found that the ozonizer draws very little power, i.e. less than 4 W with an almost constant efficiency at 90%. The maximum achievable ozone yield is 3.6 g/kWh. |
