A full bridge driver circuit with modulated input voltage using buck-boost converter for LED lighting systems is proposed. A dc voltage source, which is in series, processes portion of lamp power without conversion. Small controlled power is supplied through full bridge circuit. In the proposed configuration, current stress of switches in full bridge is greatly reduced. In addition, zero-voltage switching (ZVS) is accomplished in full bridge devices. Input voltage variations can be compensated to maintain constant LED lamp current. All LED lamps are dimmed simultaneously using on-off control. The circuit description and analysis are discussed in detail and it is validated experimentally.
