5.3. Pad Driver Module
When the IGBT (U9) is opened, the current flow over the “PAD”. The “PAD” is a coil, so it will
save the power. The current direction is from left to right. Once the IGBT is closed, because
the
“PAD” is a coil, the current direction is still from left to right. Because there is a C11, so it
and the
“PAD” are made an oscillation loop, and the power will be saved in the C11. When
the system is working, if there is a cooker on the
“PAD” coil, the cooker will be heated.
