EVEN-LEVEL INVERTER

摘要

PURPOSE: An even number inverter is provided to efficiently control reactive power by comprising a bidirectional switching element only with transistors. CONSTITUTION: A division part(210) divides input DC power into the voltage levels of an even number. Multiple switching elements are connected to each node of the division part. Bidirectional switching elements(230) are connected to each node through at least one of the switching elements. The bidirectional switching element comprises at least 2 transistors. The division part comprises at least 2 capacitive elements.
