Title:
パルス電圧を生成する方法及び回路配置
Document Type and Number:
Japanese Patent JP2012529738
Kind Code:
A
Abstract:
The invention proposes a circuit arrangement for converting a DC voltage from a DC power supply into a pulsed voltage to operate or drive a load, for example, a DBD lamp. The circuit arrangement comprises a transformer having a primary winding and a secondary winding, a first controllable switch branch, a second controllable switch branch, and a control unit. The control unit is configured to control the first controllable switch branch and the second controllable switch branch to be alternately turned on so that at least part of the energy from the DC power supply is stored in the primary winding during each turn-on period of the first controllable switch branch and the second controllable switch branch, and to leave an idle time between the two adjacent turn-on periods so that at least part of the stored energy is transferred to the secondary winding to alternately generate a positive pulsed voltage during one idle time and a negative pulsed voltage during the next idle time.
