THE LEAN" BUFFER CIRCUIT 3-Phase Frequency converters with Low-Capacitance DC-Link (LCDC) Robots, elevators, assembly Lines, processing centers, tooling machiĭnes - high process speed and further improvement of automation levels are unthinkable without frequency controlled AC drives. And it would not be possible to achieve the optimum operating characteristics at an economically feasible utilization level of available resources. Most of the contemporary 3-phase frequency converters are working with a DC link, mainly using electrolytic capacitors to buffer the DC voltage. When selecting the...
