A dual active bridge system can include a plurality of dual active bridges (DABs). Each DAB can have a first side connected in parallel and a second side connected in parallel such that each of the plurality of DABs share a common first side capacitor and a common second side capacitor. The plurality of DABs can be configured to be operated to reduce or eliminate ripple current at the first side capacitor and/or second side capacitor.
