Micro-dc grid is a novel power system focused on the development of renewable resources. However, two-wire transmitting power mode is generally accepted in a micro-dc grid, which is usually not suitable for the requirements of the input voltage levels of different power converters and loads. In order to meet the requirements, a half-bridge voltage balancer was introduced in a micro-dc grid, which can convert a two-wire mode into a three-wire mode in a micro-dc grid via a neutral line. However, the shoot-through problem existing in bridge-type converters degrades the reliability of the voltage balancer. In this paper, a buck and boost multiple output voltage balancer and a control strategy is presented, which can avoid the shoot-through problem. And, it is found that, a bucked multiple output of 110V DC and boosted multiple output of 300V DC was obtained when an input of 220V DC is given.
