Disclosed herein is a power supply suitable for use with an airfield lighting device. In accordance with an example embodiment, there is disclosed herein, a rectifier that converts a signal from an alternating current (AC) current source to a direct current (DC) voltage. The circuit comprises a current sensor, a controller, and a half active bridge rectifier. The controller receives a signal from the current sensor and controls the operation of the half active bridge rectifier to produce a light emitting diode (LED) current based on the current sensed by the current sensor. |
