    摘要: A starter of the grid-connected inverter and a control method thereof are disclosed. The starter comprises a controller, and a first switch and a first resistor connected in parallel. The controller includes an input end, and first and second output ends. The input end inspects the DC voltage signal from the inverter. When the DC voltage exceeds a predetermined voltage threshold, the first output end sends a first control signal to turn on the first switch, and the second output end sends a second control signal to make the grid-connected inverter enter into a chopping mode. There is a delay period between the send time of the first control signal and that of the second control signal.

    摘要: The radiance of a laser diode is a function of laser diode drive current. The radiance is also a function of other factors, such as age and temperature. A laser projection device includes laser diodes to generate light in response to a commanded radiance, and also includes photodetectors to provide a measured radiance. The commanded radiance and measured radiance are compared, and drive currents for the laser diodes are adjusted to provide luminance and color balance tracking.
