Upgraded from FFT algorithm, contributing to consistent reliable compensation, accurate analysis leading to precise compensation.
Core technology coming from diligence of R&D team, gained by accumulations of thousands site applications.
Output voltage and current is much more sinusoidal and the THD is better.
Higher efficiency Smaller heat sink Better reliability
Every phase leg consists of 6 semiconductors: 4 IGBTs and 2 Diodes, connect the module to AC and to the DC-link: DC+, DC- and N (neutral). The DC-link is split in two symmetric halves connected in series; the upper half connecting DC+ and N, the lower half connecting N and DC-. PWM with three voltage levels where the three level topology has its name from.
