The signs in the Eqs. �16�, �21�, and �23� of Ref. 1needed to be corrected. This results in the followingequations.

1. Change the sign of the IY0X1 term in Eqs.�16a�–�16d�.

Case I: �m0 � �45° and �m1 � �45°

M � �Idc �0sIY0 � IX0

�1sIY1 �0s1sIY0Y1 � �1sIX0Y1

� � � �

IX1 �0sIY0X1 � IX0X1

� . (16a)

Case II: �m0 � �45° and �m1 � 0°, 90°

M � �Idc �0sIY0 � IX0

� � � �

�1cIY1 �0s1cIY0Y1 � �1cIX0Y1

IX1 �0sIY0X1 � IX0X1

� . (16b)

Case III: �m0 � 0°, 90°; �m1 � �45°

M � �Idc � �0cIY0 IX0

�1sIY1 � �0c1sIY0Y1 �1sIX0Y1

3. Change the sign of 2 and �2 in Eqs. �23l� and�23n�, resulting in

2 � �D�2��CspSps � SspCps�, (23l)

�2 � �D�2��CSps � SCps�. (23n)
