Multi-Mode Power Converter Power Supply System

摘要

A multi-mode power supply includes both a DC-AC/DC-DC dual-mode converter and a DC-DC converter. In a first mode of operation, the DC-AC/DC-DC dual-mode converter supplies AC power to AC loads and the DC-DC converter supplies power to a mix of steady-state DC loads and transient DC loads. If the transient DC loads request power above that which is available from the DC-DC converter, then a second mode of operation is entered. In the second mode of operation, the DC-AC/DC-DC dual-mode converter ceases to provide AC power to the AC loads and instead is cross coupled with the DC-DC converter, together supplying sufficient DC power to the transient loads that requested power.

1. A power supply system, comprising:
a DC-AC/DC-DC dual-mode converter; a DC-DC converter; at least one steady state DC load, at least one transient DC load, and at least one AC load; wherein when in a first mode of operation the DC-AC/DC-DC dual-mode converter is configured to provide AC power to the AC loads and the DC-DC converter is configured to provide DC operating power to the steady state DC loads and DC standby power to the transient DC loads; wherein when in a second mode of operation the DC-AC/DC-DC dual-mode converter is cross coupled with the DC-DC converter and together supply DC operating power to at least one of the transient DC loads and the steady state DC loads.
