Power supply system with two regulated power supply devices connected in parallel at an output

摘要: A power supply system is disclosed having two regulated devices with outputs connected in parallel for redundant half-load operation. Each device has a voltage regulator and current to switching transistor which provides regulation. discriminator transfer switch each compares sensed load currents both the switches from regulation or vice-versa. By use of discriminator, an active, reaction-free take over case failure one operating mode may be accomplished. The other then switched so as failed.
