Parallel connected power supplies having parallel connected control circuits which equalize output currents to a load even after one supply is turned off |
摘要 |
A power supply system comprises several power supplies, each of which has output terminals that are coupled in parallel to supply respective DC output currents at the same time to a single load. Each power supply also has a branch of a control circuit, and each branch from every supply is coupled in parallel to thereby form a complete control circuit. In these branches, control currents flow that cause the respective output currents from the several power supplies to equalize. Each power supply also has a circuit for automatically turning the supply off independent of the other power supplies when a component in the supply fails; and under such conditions, a switch in the control circuit branch of the failing supply automatically opens which prevents control current from flowing therein and enables the remaining supplies to share the added load.
