The significantly improved device parameters allow the replacement of two paralleled OptiMOS 5 BSC030N08NS5 power MOS-FETs in each position of the primary full bridge with one OptiMOS 6 ISC014N08NM6 power MOSFET. Figure 4 compares the efficiency and device temperatures. With the new devices, ...
However, the remarkable increase in cell density has also brought to light significant disadvantages. The gate-drain capacitance and gate-source capacitance both increase linearly with the number of trenches, i.e. with the cell density. Together with a sublinear sc...
The prior art illustrated in FIG. 1 has obvious advantages of self-aligned trenched source-body contact to the gate trenches101due to formation of the contact openings106is implemented by formation of the gate trenches portion that fan out. However, there are still some disadvantages constraining...
The channel depth is proportional to the gate voltage and pinches closed as soon as the gate voltage is removed, so there is no storage time effect as occurs in transis tors. Rev B, October 1998 The major disadvantages are: 1. High resistance channels. In normal operation, the source is...
Its disadvantages, however, are high cross conduction currents, as well as requiring excessive supply current when the output is in the low (OFF) state. This leads to higher power dissipation and junction temperature than optimum. This brings us to newer ICs designed specifically as power MOSFET...
because the switching loss and conduction loss are doubled. This topology also requires two output inductors, which brings additional costs and the cost of PCB space. In this article, we will discuss in detail the relative advantages and disadvantages of half bridge and full bridge operation of ...
