Working Principle

The MAP42-1012G AC-DC converter is designed to operate as a transformerless, switch-mode power supply. It is composed of a power stage, a control stage, and a protection stage. The power stage comprises an input rectifier, a high-frequency half-bridge DC/DC converter, and the output filter. The control stage includes a soft-start circuit, a high-frequency oscillator, and a pulse width modulation (PWM) controller.

The input rectifier rectifies the AC input into a DC voltage. This voltage is then fed into the high-frequency half-bridge DC/DC converter, which in turn converts the DC voltage into a high-frequency AC voltage. The output filter then converts this AC voltage into the desired DC output voltage.

The control stage is responsible for the regulation of the DC output voltage. The soft-start circuit limits inrush current at initial startup. The high-frequency oscillator produces a low-jitter square wave used to drive the PWM controller. The PWM controller generates the signals that switch the output devices of the power stage, thus controlling the output voltage.

The protection stage provides a variety of protection features, such as overvoltage protection, overcurrent protection, short circuit protection, and thermal protection. It is designed to protect the MAP42-1012G from potential damage during operation.

The MAP42-1012G is a reliable and efficient AC-DC converter that can provide power to embedded systems and other applications. It is capable of delivering up to 120W of power with high efficiency, and its wide range of input and output voltages makes it an ideal solution for many applications.
