Energy level conversion circuit for portable energy storage apparatus
Provided is an energy level conversion circuit for a portable energy storage apparatus, and includes a motherboard circuit to connect a plurality of sub-board circuits in series through female connectors, wherein the sub-board circuits receive input of direct current (DC) power, convert it to a preset energy level and output it, and the sub-board circuits connected or inserted into the motherboard circuit through the female connectors, and including a switching unit which is switched by a pair of switching pulses (P1, P2) applied from the motherboard circuit, so that when each switching transistor (Q1, Q2) is on/off, power transformed through a transformer is outputted through secondary side transformer tap connection terminals (T1, T2), wherein the sub-board circuits are connected in series through a female connector unit of the motherboard circuit, so that DC power whose energy level is converted as much as the number of the sub-board circuits is outputted through the motherboard circuit.
