Figure 5. Full wave control description
Full wave pulse control is based on sending gate control pulse immediately after ZVC
signal. Gate control pulse length is defined by the software.
Refer to
for default gate current pulse duration for all AC switches. Duration of each
pulse is set separately for 50 Hz and 60 Hz mains.
