摘要： A highly efficient rectifier can readily replace a two-terminal diode. Its conduction losses are reduced from that of the two-terminal diode. Connected between the source and drain of a MOSFET including a parasitic diode are a micro-power converter section for boosting a conduction voltage Vds between the source and drain to a predetermined voltage, and a self-drive control section that operates based on a voltage output from the micro-power converter section. When the source and drain are conductive with each other, the micro-power converter section generates, from the conduction voltage Vds, a power source voltage for the self-drive control section, and the self-drive control section (4) continues drive control of the MOSFET.

摘要： A projection display uses a light modulating device to modulate, in accordance with image data, light radiated from a light source, project the modulated light onto a screen, and display an image. The projection display separates a unit of time configuring the image data into an effective light time when the light modulating device can express the light as an image on the screen and an ineffective light time when the light modulating device cannot express the light as an image on the screen. The projection display increases the power supplied to the light source during the effective light time over the power supplied to the light source during the ineffective light time.
