TITLE : Overload Protection System for Power Inverter

SUMMARY :
An overload protection system for a power inverter utilized a first
circuit for monitoring current to the load from the power inverter to
detect an overload and a control circuit to shut off the power inverter,
when an overload condition was detected. At the same time, a monitoring
current inverter was turned on to deliver current to the load at a very
low power level. A second circuit monitored current to the load, from
the monitoring current inverter, to hold the power inverter off through
the control circuit, until the overload condition was cleared so that
the control circuit may be deactivated in order for the power inverter
to be restored after the monitoring current inverter is turned off
completely.
