AC DC converters are electronic devices used to convert alternating current (AC) to direct current (DC), and are an integral part of virtually all portable electronics, such as cell phones and laptop PCs. The QS10.241 exponential voltage search circuit, also known as an EVSC, is an advanced AC-DC converter used to power a wide range of digital and analog application fields. This article will explain the working principle and application fields of the QS10.241 EVSC.

Principle of Operation

The QS10.241 EVSC is a high efficiency voltage search circuit, designed to find the optimal operating point in a two quadrant AC-DC converter. The circuit operates by combining a switching PWM voltage regulated power supply with a voltage search loop, which is designed to track the input AC voltage and automatically adjust the output DC voltage to match the available AC voltage. This ensures that the output DC voltage remains within the optimal operating range and harmonic distortion is minimized.

The QS10.241 EVSC utilizes a standard PWM voltage regulation scheme to modulate the output current, ensuring that the output DC voltage is within the acceptable range. This is accomplished using a proportional-integral-derivative (PID) controller, which is programmed to maintain the output DC voltage at a given level, independent of the input AC voltage. In addition, the EVSC includes a voltage search loop, which provides a safe and reliable means of achieving power conversion.

Application Fields

The QS10.241 EVSC has a wide range of applications, including digital and analog electronics, instrumentation, and communications systems. The most notable application fields include the following:

• Power MOSFET and IGBT-based AC-DC converters
