Document Type and Number:
Japanese Patent JP3366677
Kind Code:
B2
Abstract:
An audio amplifier output stage comprises first and second solid state devices, each having a controlled current conducting path comprising first and second terminals and a controlling current conducting path, comprising at least a third terminal. The output stage also includes an uncontrolled current conducting path in antiparallel relation with each of the devices' controlled current conducting paths. A saturable reactor is positioned in series with the uncontrolled current conducting path to limit current flow therethrough during the switching of current flow from the controlled current conducting path of one of the devices to the uncontrolled current conducting path occasioned by operation of the amplifier.
