摘要

A boost converter, which allows stable control without breaking or losing the output balance of each converter unit (3,3A) in parallel, has current transformers (22,23) which are connected in series respectively to a switching element (7) and a diode (8). The current transformers (22,23) detect current and allow current detection signals to be output from current detection circuits. The current detection signals obtained from one converter unit (3) are compared with the current detection signals obtained from another parallel converter unit (3A) by a comparing circuit (33). The DC output voltage Vout of each converter unit can be controlled to be equal to each other.
