Abstract

The invention belongs to the technical field of power control, and provides a free piston linear generator power adjusting device and method based on voltage adjustment. The free piston linear generator power adjusting device based on voltage adjustment comprises a current control unit and an output control unit. The current control unit is used for obtaining the segmented control condition of thegenerator, the magnitude of each segment of current and the action time according to the external output power requirement and the relationship between the electromagnetic force and the magnitude ofcurrent, and calculating the voltage required in a segmented control interval according to the relationship between the voltage of the generator and the current; and one end of the output control unitis connected with the power supply of the generator, and the output control unit outputs the voltage required in each segmented control interval based on the Boost principle and applies the voltage to a motor. According to the free piston linear generator power adjusting device, the required voltage is obtained by utilizing the current rate, so that the purpose of quickly adjusting the power of the generator is achieved.

Description

technical field [0001] The invention belongs to the technical field of power control, and in particular relates to a voltage regulation-based free-piston linear generator power regulation device and method. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The free-piston linear generator is a new type of energy conversion device formed by the coupling of a free-piston internal combustion engine and a linear generator. Its thermal efficiency is higher than that of traditional engines, and it can play a significant role in energy saving, emission reduction and environmental pressure relief. The free piston linear generator mainly includes two main parts, the engine and the generator. When starting, the generator acts as a motor to drive the piston to the top dead center to complete the first cycle process; The rapid movement driven by the pi...
