用于直流微电网的ZVS-ZCS高升降压隔离双向DC-DC变换器

A soft-switched isolated bidirectional dc–dc converter is proposed for distributed generation systems. Dual coupled inductor-based flyback energy conversion circuit achieves high-voltage step-up/down ratio and high efficiency at lowered duty cycle and, attributes the galvanic isolation. Active switch-based capacitor multiplier cell appreciably reduces voltage stresses on low-voltage (LV) and high-...
