Schematic
Although the schematic is not very complex, this section presents the different parts as
separate topics:
●
Mains, DC link and zero voltage switching
●
Isolated power supply
●
Power stage
●
Feedbacks
●
MCU pin configuration
The user interface schematic is not presented in this section. It is discussed and analyzed in
Section 8.
3.1
Mains, DC link voltage and zero voltage switching
Figure 2.
Mains and +325 volt DC link
The mains is filtered and is not applied directly to the power diode bridge: for safety reasons,
it goes through a relay. This means that the DC link voltage is not applied to the IGBT while
the system is off.
The 14 V DC relay is driven by the MCU through a classic NPN transistor. An LED is also
present.
When the system is on - and the AC line is applied to the power diode bridge - the IGBTs
are supplied with +325 V. The resistive divider sends an image of the DC link voltage to the
MCU (label VLINK). The last part of the schematic is an isolated zero voltage switching
(ZVS): a square waveform at 50 Hz synchronized with the mains (label 50 Hz).
