20110043177	CONTROL DEVICE FOR AN INTERLEAVING POWER FACTOR CORRECTOR - In an interleaving power factor corrector, a control device interleavingly drives first and second converting circuits such that the power factor corrector generates a voltage output (Vo), and includes first and second control modules generating respectively first and second driving signals (Q_master, Q_slave) that correspond respectively to first and second control signals for controlling operations of power switches of the first and second converting circuits. A phase modulating module generates a reset signal (S_PTCL) based on an inverted first driving signal (Qn_master) and a feedback compensation signal (Vcomp) outputted by the first control module, and a reset signal (S_syn) outputted by the second control module. When one of the reset signals (S_syn, S_PTCL) has a predetermined level, the second driving signal (Q_slave) has a level for switching the power switch of the second converting circuit to an OFF-mode.	02-24-2011

20080316775	Soft-switching circuit for power supply - A soft-switching circuit for a power supply comprises a bridgeless rectifier circuit and an auxiliary circuit. The auxiliary circuit is connected to the bridgeless rectifier circuit, which comprises at least one filtering inductor, two main switches, two diodes and a capacitor. The filtering inductor is connected to the first diode. The first diode is connected to the second diode. The second diode is connected to the first main switch. The first main switch is connected to the second main switch. The diodes and the main switches are connected in parallel with the capacitor to reduce conducting loss. The auxiliary circuit comprises at least one resonant inductor, an auxiliary switch, at least two diodes and a voltage source circuit. The diodes are connected to the resonant inductor and further connected to the voltage source circuit. The voltage source circuit is connected to the auxiliary switch, whereby the soft-switching circuit can accomplish zero voltage switching and zero current switching to provide low conducting loss and low switching loss.	12-25-2008
