Methods and systems are provided for controlling the output power to DC electric heater elements to reduce the input current ripple and to fine-tune the output power to meet the fine-tuning percentage requirement. In one embodiment, a method is performed for controlling output power to heater elements in an electric heater system. The process includes receiving a power request by the heater system, providing output power controls for each heater element, and determining a particular output power control based on output power controls provided for each heater element and the power requested. Further, the heater system selectively controls the output power to one or more of the heater elements to meet the power request.
