| Zusammenfassung: | A solar energy powered lamp driver ( 100; 200 ) capable of driving a gas discharge lamp (L) comprises:-a half-bridge inverter ( 130 ), comprising: a first branch of two controllable switches ( 131, 132 ) coupled in series between a first reference node (VI) and a second reference node (mass); a second branch of two buffer capacitors ( 133, 134 ) coupled in series between said first reference node (VI) and said second reference node (mass); an output branch (DE) connected between on the one hand a first node (D) between said two controllable switches ( 131, 132 ) and on the other hand a second node (E) between said two buffer capacitors ( 133, 134 ); a boost converter ( 110 ), having an output ( 115 ) connected directly to said first node (D) between said two controllable switches ( 131, 132 ). |
