Latest Patents

Dorota holds a patent for a "High frequency driver for gas discharge lamp." This invention involves a driver that is supplied with a DC voltage, which is then converted to an AC voltage. The AC voltage is supplied to a load that includes a gas discharge lamp, an inductor connected in series with the lamp, and a capacitor connected in parallel to the lamp. The driver operates at a first high frequency during the ignition of the lamp and a second high frequency during normal operation. Notably, the first frequency is higher than the second frequency by a ratio of at least 2.2. This modulation of frequency allows for compliance with EMI and RFI requirements while enhancing performance.
