VRGLH is the maximum value and VRGLL is the minimum value of the coupling waveform during the period from

Point A in the above diagram until the rising edge of RG. In addition, VRGL is the average value of VRGLH and

VRGLL.

VRGL = (VRGLH + VRGLL)/2

Assuming VRGH is the minimum value during the period twh, then:

VφRG = VRGH – VRGL
