The GE IC698PSA350D power module is a power converter that can be mounted directly on the printed circuit board, which is generally divided into AC to DC or DC to DC according to the conversion mode. With the development of science and technology, the volume of power supplies tends to be modular and miniaturized, so there is a power module. The main circuit of the switching power supply is integrated in the chip, which can realize the functions of broadband modulation, isolation and a variety of protection.

The common basic principle of the GE IC698PSA350D power module consists of the following parts: the input rectifier filter, including the rectifier bridge and the input filter capacitor. Monolithic switching power supply, including power switching tube, controller and MOSFET. There are also high frequency transformer, leakage clamp protection circuit, optocoupler feedback circuit, output rectifier filter, bias circuit and other parts. The power module can generally adapt the input voltage range of AC 85~265V or DC 100370V through the input rectifier filter, and the frequency is 47400Hz, and the general frequency is 50/60Hz. Because it has a small size, high integration, high cost performance and the best performance indicators, only the simplest peripheral circuit is required, with a small number of discrete components can be used. And has the advantages of high efficiency, high reliability, flexible design, etc., has become the optimal integrated circuit for the development and design of small and medium power switching power supply.

The GE Automation and Control division combines what was formerly known as GE Intelligent Platforms and Alstom's Power Automation and Control. In 2019, GE Smart Platforms was acquired by Emerson Electric and is now known as Machine Automation Solutions.

GE Automation & Controls produces programmable logic controllers (PLCS) and programmable Automation Controller-based (PAC) control systems, I/O, and field equipment, including support for the design, commissioning, and operation of industrial assets and operations. Industries served include manufacturing, food and beverage, life sciences, power, oil and gas, mining and metals, water and wastewater, and specialty machinery industries.
