| Zusammenfassung: | The invention discloses a microcomputer system power emergency conversion circuit which comprises a switching power supply, a storage battery, a load and a conversion module. The switching power supply, the load and the conversion module are connected in series to form a switch power supply circuit. The storage battery, the load and the conversion module are connected in series to form a storage battery power supply circuit, and the switching power supply and the storage battery are connected in parallel to form a float charging circuit. The mutual switching of the switch power supply circuitand the storage battery power supply circuit under power obtainment and power loss states of mains supply can be realized through the conversion module. Through the above mode, the storage battery canbe charged when the switching power supply supplies power, the power supply of the switching power supply and the storage battery can be automatically switched by a microcomputer system load under the conditions of power obta |
