CIRCUIT FOR CONVERTING DC INTO AC PULSED VOLTAGE |
摘要 |
<p>The present invention proposes a circuit for converting DC into AC pulsed voltage. The circuit comprises two controllable semiconductor switches. By controlling the opening and closing of the semiconductor switches, the circuit can operate in different modes, i.e. high input voltage mode and low input voltage mode. The circuit for converting DC into AC pulsed voltage, proposed in the present invention, is suitable for a wide input voltage range. When the circuit is used as the driver circuit of a DBD lamp, the DBD lamp can still operate normally by switching to low-voltage DC supply in case of an AC supply failure, and the DBD lamp has a higher luminous efficiency.</p> |
