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. Five 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 of7805. For each U, V, W phase side: +15V for VB(U, V, W) and VS(U, V, W) operation of SPM.
