摘要： A non-isolated AC/DC converter having power factor correction, comprising an active switch connected to a waveform controller for control, and sequentially showing conduction, cut off, making the alternating current power supply pass through one circuit rectifier for rectifying and forming one positive half sine wave electricity supply, which passes through a voltage step-down circuit to proceed with decreasing the voltage, then passing through a filter/storage circuit for filtering and forming direct current power supply, which is stored on this filter/storage circuit, then releasing the energy and supplying electricity to the electricity end; as a transformer isn't required, the circuit volume can be reduced, lowering costs, raising circuit conversion rates and achieving power factor correction and increasing the lifespan of the transformer, moreover, through the waveform controller controlling the output waveform, the storage circuit utilizes a lower capacity capacitor to avoid using an electrolytic capacitor, thereby increasing the circuits lifespan.

摘要： A variable master current mirror circuit may be used to balance the currents through parallel Light Emitting Diode (LED) strings in an illumination module when the LED string with the largest forward voltage changes due to events, such as a short failure of an LED. The variable master current mirror circuit includes a switching circuit that is coupled to the parallel LED strings and a current mirror circuit that is coupled to the parallel LED strings and the switching circuit. The switching circuit switchably connects the LED string with the largest forward voltage to the current mirror circuit as a master LED string. The current mirror circuit maintains equal currents through the LED strings with reference to the current through the master LED string.

摘要： In a power supplying apparatus for use in an image forming apparatus, when a first transistor is switched on, a first photo-triac coupler and a first triac switch on so that a fixing heater is powered on. After a predetermined time, a second transistor is switched on. A second photo-triac coupler and a second triac are thereby switched on so that the fixing heater is powered on. The first triac is then switched off. The first triac is connected in series to a resistor, so that when the first triac is switched on but the second triac remains off, the voltage applied to the fixing heater is sufficiently low in comparison with the voltage applied thereto when the second triac is switched on. Therefore, when the fixing heater is powered on by switching on the first transistor to switch on the first triac, a large power surge does not occur. When the second triac is switched on, a large power surge does not occur either since the fixing heater has already been powered on. Occurrence of power surges through the fixing heater is thereby reduced.
