450V560UF电子元件 全新螺丝脚电解电容器 450VDC YADACON 雅达康

Each working cycle of the full-bridge inverter is divided into four periods, respectively, which are t1t2t3k4. Its working principle is as follows: K1k4 on in T1 period, *** turn-off current direction: positive electrode K1t / c1k4k4k2, and so on, and its working principle is as follows: K1k4k4k2, K1k4k2, k1k4k2, k1k4k2. K3 turn off no current T1 K4 turn off, K2N K3 conduction current direction: positive electrode K2c1 t K3 ground T4 period k1k4*** turn off
