Abstract: An ozone generation device includes an inverter, an ozone generator, and a reactor. The inverter turns on and off a switching element by pulse width modulation (PWM) control to convert DC power into AC power. In the ozone generator, voltage of the AC power is applied to a dielectric electrode, and discharge is generated in raw material gas flowing in a discharge gap between the dielectric electrode and a metal electrode, so that ozone is generated by the discharge. The reactor is connected in series to a dielectric electrode, and reduces an inrush current that flows through the dielectric electrode when the switching element is switched from off to on by the PWM control by the inverter.

Abstract: In a method and apparatus (10) for air disinfection a unipolar corona discharge zone (26) is formed between an ionizing portion (15) of a first electrode (14) and a non-ionizing second electrode (18) by applying high DC voltage (22?, 22?) across the first and second electrodes and water molecules in an air flow (25) conveyed through the corona discharge zone are converted to hydrogen peroxide molecules. An electric field (27, 27?, 27?) is generated across the air flow close to the corona discharge zone for preventing ions escaping from the corona discharge zone into the atmosphere. This allows a higher corona discharge current to be applied than would be permitted if ions were able to escape into the atmosphere, which results in a higher yield of hydrogen peroxide and increases the efficiency of disinfection. It also helps to prevent dust from settling on the ionizing portion (15).
