“…Therefore, if frequency control is to be implemented, a narrow range of frequency control above resonance is necessary to achieve both ZVS and an acceptable voltage gain. Fixed frequency control above resonance such as phase shift control [23][24][25] overcomes the problems of variable frequency control and offers good control of the output voltage via controlling the phase-shift angle between the inverter legs; hence the effective inverter output voltage duty-cycle ratio. For the aforementioned reasons, this paper focuses on fixed frequency phase control of a SPRC.…”

“…Many non-dissipative schemes for higher efficiency were proposed in literature [1,2,3,4,5,6,8,9,10,11,12,13,14]. However, in most of the schemes, the costs are relatively high because each battery cell needs two or more electrical switches [2,5,7,9,10,11,13].…”

This paper presents a modularized buck-boost and series LC converter (BBSLCC) circuit for series battery equalizers. The proposed topology has numerous advantages. First, the number of switches in the equalizer is equal to the number of the battery cells needs to be balanced in the string. This is so called one-switch-per-cell, which is a great advantage over the traditional buck-boost converter, since it requires almost twoswitch-per-cell to balance. Second, unlike many other existing one-switchper-cell equalizers, the proposed circuit has the advantage in the modularization design and low voltage stress requirement on the switches. Third, the peak current of the balancing capacitor are suppressed by the synchronous phase-shift controller (SPSC) which can be easily implemented by sensing the zero crossing of the LC resonant current. By using the proposed controller, the speed of the battery equalizing process is also accelerated. In this paper, the proposed topology is first presented, and the operating principle is illustrated. Afterwards, the phase-shift time and the transferred energy of the BBSLCC circuit are calculated to demonstrate the proposed control strategy details. The relationships between the phase-shift time and other circuit parameters such as the inductance and the capacitance are also analyzed. The simulation results and the experimental results are finally demonstrated and verified the theoretical analysis on the performance of the proposed BBSLCC circuit.

Abstract-This paper presents an approach for nominally lossless regulation of the output voltage, and for design of tight closed-loop voltage control of a resonant switched-capacitor (ResSC) dc-dc converter. A switching pattern for the ResSC dc-dc converter that enables wide range lossless voltage regulation and zero voltage switching (ZVS) is developed. An appropriate small signal model is derived based on the generalized averaging method. In view of the dynamics of the developed small signal transfer functions, a compensation method based on a minor phase loop is introduced to stabilize the system. The steady state and transient responses of the system are evaluated based on the developed model. The performance of the proposed controller is verified by a switch-based simulation in a design example for on-chip power delivery application.
