Error in Figure
In the original publication [1], there was a mistake in “Figure 2. Control block diagram: (a) overall control block diagram of wye-connected CHB converter; (b) block diagram of total energy controller; (c) block diagram of leg capacitor energy balancing controller; (d) block diagram of current controller” as published. “Figure 2a has been incorrectly applied and is the same as Figure 2c”. The corrected “Figure 2. Control block diagram: (a) overall control block diagram of wye-connected CHB converter; (b) block diagram of total energy controller; (c) block diagram of leg capacitor energy balancing controller; (d) block diagram of current controller” appears below. The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
Figure 2.
Control block diagram: (a) overall control block diagram of wye-connected CHB converter; (b) block diagram of total energy controller; (c) block diagram of leg capacitor energy balancing controller; (d) block diagram of current controller.
