2.7.4 PCS Schematic Diagram and Circuit Design
The basic electrical schematic diagram of the CPS ECB62.5KTL-M inverter is shown below (Figure 2-10). The DC input from
the batteries connects to the DC side of the PCS inverter, passes through the DC contactor, then converts to the three-phase
AC waveform through three-level inverting technology. The high frequency harmonic distortion is removed with an output filter
and the output AC goes through the AC contactors.
