Abstract

The invention provides an integrated drive control circuit applied to a double-power feed system and a control method thereof. The double-power feed system comprises a first power supply, a second power supply, a load, an integrated drive control circuit and the like. The integrated drive control circuit also further comprises a compound switch converter connected with a controller, wherein the controller is used for controlling the operation of the compound switch converter when the energy of the first power supply is sufficient, and the first power supply outputs the energy to the second power supply. When the energy of the first power supply is insufficient, the controller controls the operation of the compound switch converter, and the second power supply transmits energy to the load.The invention realizes the operation modes of two converters by a group of compound switch converter, simplifies the circuit design and enhances the working stability.

Description

technical field [0001] The invention relates to a power supply circuit, in particular to a collective drive control circuit and its control method applied in a dual power supply system, and a dual power supply system using the collective drive control circuit and control method. Background technique [0002] In the power supply system powered by dual power sources in the prior art, generally the first power source can receive external energy and convert it into its own power source for energy storage, for example, it can be a solar cell, a fuel cell, a wind generator or a power grid power supply, etc.; and, the second The second power supply is a power supply type with energy storage characteristics, such as a storage battery. When the energy of the first power supply is sufficient, it can transfer energy to the second power supply and / or the load. When the energy of the first power supply is insufficient, the energy storage power supply, that is, the second power supply, tr...
