A converter system and method is provided. The converter system includes a converter and a control module. The converter is electrically connected with a DC bus and a load. The converter is configured to realize the conversion between a bus voltage of the DC bus and a load voltage of the load. The control module is electrically coupled with the converter. When the converter is in a standby mode, the control module generates a first-side compensation signal according to the bus voltage and generates a second-side compensation signal according to the load voltage. And the control module generates an instruction current signal according to the first-side compensation signal, the second-side compensation signal and a reference current signal. The control module generates the driving signal according to the instruction current signal, so as to control an output current of the converter to be stable.
