Title:
ENERGY LEVEL CONVERSION CIRCUIT FOR PORTABLE ENERGY STORAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/151634
Kind Code:
A1
Abstract:
The present invention relates to an energy level conversion circuit for a portable energy storage device, the energy level conversion circuit comprising: a motherboard circuit for connecting a plurality of sub-board circuits, which receive direct current power, converts the received direct current power to a specified energy level, and outputs the converted direct current power, in series through a female connector; and the sub-board circuits which are connected to or inserted in the motherboard circuit through the female connector, and are configured to output power transformed through a transformer, through secondary-side trans-tap connection terminals (T1 and T2) when a switching unit switched by a pair of switching pulses (P1 and P2) applied from the motherboard circuit and each of switching transistors (Q1 and Q1) are turned on or off, wherein the sub-board circuits are connected in series through a female connector unit of the motherboard circuit, so that direct current power, the energy level of which has been converted as many times as the number of the sub-board circuits, is output through the motherboard circuit.
