Introduction Today’s switch-mode power supplies (SMPS) are smaller, more efficient, and lower-cost than ever. The key to their performance is the power switch technologies at their heart – but how should designers choose the right material for this and find the best component to meet their needs? While silicon is the most widely-known constituent of semiconductors, a new group of wide bandgap (WBG) materials is increasingly finding its way into applications. One example is gallium nitride (

Figure 1. 3-phase inverter with two MOSFETs in parallel per switch

In applications such as motor drives, the half-bridge topology (typically 3 phases) is used to generate an AC power signal that produces a positive or negative torque in an electric motor. High output currents can be achieved only by means of paralleling MOSFETs that form each of the functional switches.&nbs

Table 1: Potential hazards from a power supply

No power supply should produce other hazards itself, which include fire, fumes, releasing dangerous chemicals, emitting harmful radiation and causing physical injury from sharp edges and falling/flying objects or burns from hot surfaces. In a power supply design, all these effects must be considered and evaluated by

Figure 1. The CM noise path and DM noise path in a buck converter

EMI from switching regulators is broken down into radiated and conducted emissions (CE). This article focuses on conducted emissions, which can be further classified into two categories: common-mode (CM) noise and differential-mode (DM) noise. Why the CM-DM distinction? EMI mitigation techniques tha tare effective for C
