Low-side cascode By using 2 MOSFET, one high-voltage and one low-voltage in a cascode configuration, we can reduce the reverse recovered charge to the Qrr of the low-voltage device. This will reduce Qrr loss but add additional dead-time loss due to ~2x Vsd. The additional conduction loss is expected to be rather low, if the ..
