Abstract: A development system and a method of an offline software-in-the-loop simulation are disclosed. A common firmware architecture generates a chip control program. The common firmware architecture has an application layer and a hardware abstraction layer. The application layer has a configuration header file and a product program. A processing program required by a peripheral module is added to the hardware abstraction layer during compiling. The chip control program is provided to a controller chip or a circuit simulation software to be executed to control the product-related circuit through controlling the peripheral module.

Abstract: A Totem-pole power factor corrector receives an input power source and convert the input power source into an output power source. The Totem-pole power factor corrector includes an input inductor, a fast-switching switch leg, a slow-switching switch leg, a resonant tank, and an output capacitor. The fast-switching switch leg includes a fast-switching upper switch and a fast-switching lower switch, and the fast-switching upper switch and the fast-switching lower switch are commonly coupled at a first middle node. The slow-switching switch leg is coupled in parallel to the fast-switching switch leg, and the slow-switching switch leg includes a slow-switching upper and a slow-switching lower switch. The resonant tank includes a resonant inductor and at least one resonant capacitor. A first end of the resonant inductor is coupled to the first middle node, and a second end of the resonant inductor is coupled to the at least one capacitor.

Abstract: A power conversion system with ripple injection includes an AC-DC conversion unit, a voltage regulation unit, at least one DC-DC conversion unit, at least one load, and a first control unit. The voltage regulation unit provides a DC link and receives one portion of an input power as an energy storage power. Each DC-DC conversion unit receives the other portion of the input power as an output power. The at least one load correspondingly receives the output power for being supplied power. The first control unit is coupled to the DC link, the at least one DC-DC conversion unit, and the at least one load. The first control unit controls the at least one DC-DC conversion unit to adjust a magnitude of a ripple of the output power to perform a ripple injection operation according to a magnitude of a ripple of the input power.

Abstract: A dual mode charge control method includes steps of: detecting an input voltage of the resonance tank, a resonance current of the resonance tank, an output current of the load, and an output voltage of the load; performing a single-band charge control when determining a light-load condition or a no-load condition of the load according to the output current; compensating the output voltage to generate an upper threshold voltage in the single-band charge control, and acquiring a resonance voltage by calculating the resonance current by a resettable integrator; comparing the resonance voltage and the upper threshold voltage to generate a first control signal; generating a second control signal complementary to the first control signal by a pulse-width modulation duplicator; providing the first control signal and the second control signal to respectively control a first power switch and a second power switch of the resonance circuit.
