In the paper, the new hybrid LED driver is proposed. The hybrid LED driver combines the idea of pulsed power conversion of a conventional LED driver with the idea of adjusting configurable LED strings synchronously with input voltage like in a direct AC LED module. This synthesis promises to increase efficiency and reduce electromagnetic interference. Due to low power loss a hybrid LED driver is attractive for circuit integration to reduce size and cost compared to the traditional LED drivers. But in the hybrid LED drivers of previous arts the topology exploits LEDs in switch-pulse mode operation, which limits the efficiency because of LEDs slow nature. In addition, the light intensity of the LEDs decreases in pulsed mode. Therefore the new hybrid LED driver is proposed to overcome the drawbacks. The attention was paid to preventing LEDs from hard switching to improve efficiency and alleviate EMI issues. To confirm the results obtained, computer modeling was performed using specialized software.
