Abstract: A green power converter which omits the pulse width modulation (PWM) technique in the traditional power converter, does not have high-frequency power device, does not generate EMI interference, simultaneously adopts the symmetry basic primitive (SBP) technique, the amplitude high modulate (AHM) technique and the dynamic rectification (DR) technique, and only needs to perform traditional power conversion on a small part of the input power so as to acquire the whole output power, namely that a large part of the output power neither need traditional power conversion nor need to pass through a magnetic core transformer. The input AC voltage neither needs to be rectified and filtered nor has large inductance and large capacitance, thus the power factor is 1, and the total harmonic distortion (THD) is 0. A transformer secondary side adopts dynamic rectification, can acquire a DC circuit, and can also acquire an AC voltage.

Charging efficiency is close to 100%, and charging and discharging are completely based on the characteristic curve of the battery All functions of a battery system, a charging system, a discharging system and a maintenance management system are realized only by a simple circuit, and no overcharge, overheating, over discharge, over current or short circuit occurs. The terminal voltages of all monomer batteries are completely equal when charging is finished, and no equalized charging is required.

Abstract: A lithium ion power battery lossless charger adopts a charging method of overall serial constant-current and monomer parallel constant-voltage to realize lossless charging on lithium ion power batteries. Lossless includes two implications: one is that charging efficiency is close to 100%, and charging power is basically lossless; and the other one is that charging and discharging are completely based on the characteristic curve of the battery, and the battery per se is completely free of damages in charging and discharging processes. The lossless charger spares a battery management system, all functions of a battery system, a charging system, a discharging system and a maintenance management system are realized only by a simple circuit, and no overcharge, overheating, over discharge, over current or short circuit occurs. The terminal voltages of all monomer batteries are completely equal when charging is finished, and no equalized charging is required.
