According to the control requirements of modular power used in energy storage systems, a parallel control strategy for bi-directional DC-DC converter is proposed and applied to the bi-directional DC-DC converter combined by current-fed half bridge and voltage-fed half bridge. While converters operate in parallel, the master-slave control based on digital communications can solve the problem of unequal...
To promote the wide acceptance of electric vehicles (EVs), the charging facilities should satisfy with some basic requirements, such as high efficiency, low harmonic pollution, long lifetime, low cost, and ease of bulk construction. Therefore, a novel EV charging facility — dc charging spot and a lower stress zero current switch-pulse width modulation (ZCS-PWM) Superbuck converter suitable for output...
The current-voltage-fed bidirectional dc-dc converter, which refers to a current-fed inverter at low voltage side and a voltage-fed inverter at high voltage side, can realize zero voltage switching (ZVS) for the switches with the use of phase-shift (PS) technology. However, the current-fed switches suffer from high voltage spike and high circulating conduction loss. In order to solve these problems,...
The current-voltage-fed bidirectional DC-DC converter can realize ZVS for the switches with the use of the phase-shift (PS) technology, however the current-fed switches suffer from high voltage spike and high circulating conduction losses. In order to solve these problems, a novel phase-shift plus PWM (PSP) control ZVS bi-directional DC-DC converter is proposed, which adopts active clamping branch...
