Abstract: A phase shift full bridge power converting system and a control method has the phase shift full bridge power converting system with a power converter, a controller, a load state detecting module, a switching controller, a switch module, a command generating module, a comparator, and a modulator module. The load state detecting module interfaces with the power converter and the switching controller. The load state detects module detects load parameter data of the power converter and switches a state at an output by using the switching controller. The controller obtains an error value between an output voltage of the comparator and a command voltage and calculates a duty cycle parameter by using the error value. According to the duty cycle parameter, a pulse control signal is generated to be outputted to a drive module for controlling the driving of the power converter.

Abstract: An uniformly self-luminous keyboard device comprises a housing and a keyboard unit. The housing includes an upper casing and a lower casing, which can be assembled together. After the upper casing and the lower casing are assembled together, an accommodation space is formed therebetween. The upper casing has an opening interconnecting the accommodation space. The keyboard unit is arranged in the accommodation space and includes a plurality of press members passing through the opening and moved by a force to have a displacement, and a baseplate supporting the press members. A light conduction space is formed between the baseplate and the lower casing. A light emitting unit is arranged inside the light conduction space. The height of the light conduction space decreases with the distance to the light emitting unit, whereby light is uniformly distributed over the bottom of the keyboard unit. Thus is achieved the uniformly self-luminous keyboard device.

Abstract: A level-switching device is coupled to an output node of a PWM converter to switch the output voltage of the PWM converter between two levels by switching a MOS. An undershoot/overshoot eliminator is coupled to the MOS for the MOS changing from totally on state to totally off state or vice versa softly when switching the MOS. The feedback signal transition in the level-switching device becomes slower when switching the MOS to eliminate overshoot/undershoot on the output voltage.

Abstract: A hybrid light source system is disclosed. The hybrid light source system adapted to be used in a projection apparatus comprises a dichroic component, a first light source, a second light source and a light processing component.
