Problems solved by technology

[0008] First, the independent DC-to-DC converter can only realize step-down conversion or only step-up conversion, that is, it can only work in one direction;
[0009] Second, when the above-mentioned independent DC-to-DC converter charges the energy storage unit, it limits the operating voltage range of the entire system
[0010] Third, all independent DC-to-DC converters have a high cost in themselves, and will bring additional electrical connection costs after being used in combination with other equipment, and also require a large installation space and bring a large difficulty of installation

Embodiment Construction

[0040] In order to better illustrate the present invention, further description will now be made in conjunction with the embodiments and accompanying drawings.

[0041] Such as figure 1 Shown is a functional block diagram of the standard inverter 1 involved in the present invention. The main function of the standard inverter 1 is to convert the DC power received by the DC high-voltage input interface into AC power and output it through the AC high-voltage output interface. The low-voltage power supply and signal interface are used to transmit the electric energy of the low-voltage power supply, the control signal from the upper controller, the signal from the motor encoder and the signal from the temperature sensor to the main control chip of the standard inverter 1 . The signal from the motor encoder and the signal from the temperature sensor are relevant signals when the present invention drives the motor. The low-voltage power supply is used to provide the working voltage...

Abstract

The invention discloses a multifunctional inverter available for battery charging and drive, and relates to the electric technical field of alternating current (AC) and direct current (DC) mutual conversion. The multifunctional inverter available for the battery charging and the drive comprises a standard inverter which achieves DC to AC conversion, a common DC bus, a logic control port, an electromotor port, an energy storage port, an AC power source port, a DC power source port, an AC to DC conversion module, a first DC to DC conversion module, a second DC to DC conversion auxiliary module and a third DC to DC conversion auxiliary module. The multifunctional inverter available for the battery charging and the drive is highly integrated, and achieves all the functions of AC to DC conversion, DC to DC conversion and the DC to AC conversion.

Description

technical field [0001] The invention relates to the electrical technical field of mutual conversion between alternating current and direct current. Background technique [0002] In the fields of fixedly installed industrial equipment, or mobile equipment (vehicles, ships, aircraft, etc.) using hybrid and pure electric power, various forms of power conversion are required: AC to DC, DC to DC and DC to AC etc. [0003] Generally, rectifiers are used to convert electric energy from various AC power sources (public AC power grid, alternator, etc.) A kind of direct current or mutual conversion, the voltage level between the two is different; the inverter is used to convert various direct currents into alternating current for subsequent equipment (such as motors). [0004] Industrial electromechanical equipment relies on the public AC power grid or alternator for power supply. When the AC power is connected, it is often necessary to convert the alternating current into direct cu...
