Flying Capacitor Topology for Ultra Efficient Inverter Applications - Nov/Dec 2020
   November 20, 2020
 
High efficiency and reduced effort for filtering are the main arguments for three-level (3L) topologies. Actually, there are several 3L topologies used in solar applications. The limitation of all Neutral Point Clamped (NPC) three-level topologies is the fact that a 150 Hz ripple has to be filtered with DC capacitors, which are independent on the frequency of the Pulse With Modulation (PWM). With high frequency and utilization of SiC semiconductors it is possible to reduce the size of the output
