CONVERTER

摘要

A converter includes a voltage selector which employs IGFETs as voltage switching elements, and a controller which controls the IGFETs. Each of the IGFETs in the voltage selector is made either the P-channel type or the N-channel type, depending upon a voltage level to be thereby switched and a level of a binary signal supplied from the controller. As a result, a voltage of comparatively great level can be switched by a binary signal of small level amplitude.
