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 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.
