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 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 power conditioner includes a power converter module, a detector module and a control module. The power converter module performs power conversion upon a three-phase AC power input from a first microgrid based on a PWM output to generate a three-phase AC power output for a second microgrid. The detector module detects the three-phase AC power input, and a first zero sequence current input that is received by the power converter module from the second microgrid. The control module generates the PWM output based at least on a result of the detection, such that the power converter module further receives, from the first microgrid, a second zero sequence current input which is anti-phase with the first zero sequence current input.
