SPV1020 description
SPV1020 is an IC designed to control a boost with a 4 phases interleaved topology supplied
by photovoltaic panels.
In a 4-phases topology the inductor-switch-diode branch is cloned 3 times and the resulting
4 branches are connected in parallel. The resulting scheme is showed below:
Figure 8.
SPV1020 drives the 4 switching elements with the same waveform but shifted of T
In order to increase the application efficiency each diode can be replaced by a switching
element driven complementary respect to the correspondent switch. Furthermore, these 4
more switching elements (synchronous rectifiers) must be driven in order to avoid any
current flow from output toward input.
SPV1020 integrates 4 Zero Crossing Blocks, one for each branch. Their role is turn off the
related synchronous rectifier to prevent reverse current flow from output.
