Another way to manage thermals is through IC packaging. Smaller and smaller packages continue to be introduced as output currents trend upward. Learn more about the packaging technologies that aid heat dissipation under these challenging conditions and enable high power density.
In recent years, resonant converters have become more popular and are widely applied in various applications like servers, communications and consumer electronics. The resonant converter can easily achieve high efficiency and allow high frequency operation with its intrinsic wide softswitching ranges. However, resonant converters rely on frequency modulation (FM) to achieve voltage or current regulation instead of traditional pulse width modulation (PWM).
With the development of telecommunication and mobile technologies, smart phones, tablets and notebook computers became essential parts of everyday life. Because of this, we require more powerful processors, which requires increased batter size and higher levels of AC/DC chargers, while the size is expected to remain the same or grow smaller.
This course demonstrates how an active clamp flyback converter achieves zero voltage switching (ZVS) and recycles the leakage energy of the transformer to improve efficiency in higher frequency operation. Although it is well known that switch node capacitance determines the circulating energy for ZVS, the capacitance-nonlinearity impact from each of the two primary-side switches and from the secondary synchronous rectifier has not been well understood.
Today, the most popular medium and high power audio amplifiers employ a Class-D working scheme due to high efficiency and excellent linearity. Compared to traditional analog amplifiers, Class-D uses high frequency pulse width modulation, similar to a switch mode power supply. Even though Class-D amplifiers incorporate negative feedback on supply voltage, the reality is that the output impedance of the power supply has an impact on audio quality.

Why should I take this training?
Loop gain measurements show how stable a power supply is and provide insight to improve output transient response. This four-part training video series discusses the theory of open-loop transfer functions and empirical loop gain measurement methods. It also demonstrates how to configure the frequency analyzer and prepare the power supply under test for accurate loop gain measurements. Examples are provided to illustrate proper loop gain measurement techniques.
