Schematics and External Interface Diagram
Note)
1. Dead time of > 10µs would be required in order to prevent a inverter-leg from being arm-short.
It depends on the optocoupler’s characteristics. In this board, a slow and low-cost type of optocoupler
is selected.
2. Two isolated power supplies are required.
For the primary side: +5V for CPU operation.
For the secondary side: +15V for SPM operation. +5V is generated by the use of the voltage regulator
