Equipment manufacturers in the field of power electronics attempt to offer their products, such as electric drives, inverters for solar systems or UPSs in the most cost effective and space saving manner. For this reason, when driving modules in the low power range, they often resort to driving the power semiconductors with 0V (unipolar), instead of the usual negative turn-off voltage such as -8V to -15V (bipolar).
