| Description: | In this paper, a configuration of a single-stage AC-DC converter and a high voltage resonant controller IC L6598 for LED street light driver is discussed. The converter is obtained by integrating two boost circuits and a half-bridge LLC resonant circuit. A voltage double rectifier circuit is adopted as output to lower the voltage stress on transformer and the associated core. The two boost circuits work in boundary conduction mode (BCM) to achieve the power factor correction (PFC). The converter works in soft-switching mode allowing the power switches to operate in zero-voltage-switching (ZVS) and the output diodes to operate in zero-current-switching (ZCS). This reduces the switching losses and enhances the efficiency. The converter features lower voltage stress on the power switches and the bus voltage is reduced to slightly higher than the peak input voltage. Therefore, the converter can perform well under high-input-voltage. Here, the DC bus and the output filter capacitances are greatly reduced. So, electrolytic capacitor-less converter can be realized for a long lifetime LED driver. Simulation results from PSpice are presented for a 100-W prototype. |
