Lamp driver using solar cells
First Claim
1. Solar energy powered lamp driver (100;
-
200) capable of driving a gas discharge lamp (L), comprising;
a half-bridge inverter (130), comprising;
a first branch of two controllable switches (131, 132) coupled in series between a first reference node (V1) and a second reference node (mass);
a second branch of two buffer capacitors (133, 134) coupled in series between said first reference node (V1) 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).
