Drive circuitry for dc systems

Abstract

A driver circuit, including a microcontroller and an output signal generator is provided. The microcontroller generates a startup control signal received by the startup control signal. The output signal generator provides, in response to receiving the startup control signal, a startup output signal to a load. The startup output signal is based on a DC power signal provided by a DC power source. The load may be a TLED luminaire. The startup output signal may be a sinusoidal or square waveform. The microcontroller receives a feedback signal corresponding to the load. The microcontroller generates, in response to receiving the feedback signal, a drive control signal. The output signal generator receives the drive control signal and provides, in response to receiving the drive control signal, a drive output signal, such as a DC signal, to the load. The drive output signal is based on the DC power signal.
