Working Principle

At the heart of the APTGL700SK120D3G is a fast-and-soft switch, which combines the capabilities of a fast switch and a soft switch. The fast switch is designed to provide high-speed switching and to eliminate the need for a separate heat-sinking component. It consists of an IGBT and an anti-parallel diode, which are connected in series and are encapsulated in a single module. The fast switch operates at a maximum frequency of 20 kHz and, in conjunction with the soft switch, is able to work within an extremely wide operational range.

The soft switch, which consists of two MOSFETs connected in series, provides precisely controlled switching at lower frequencies, allowing for greater accuracy. It also permits the conversion of high energy pulses into low energy pulses, reducing power losses and enabling the APTGL700SK120D3G to operate in a wide range of temperatures. When the module is powered, the IGBT and MOSFETs switch in sequence, allowing for efficient operation over a range of input voltages and currents.

By merging fast and soft switching, the APTGL700SK120D3G offers an exceptionally wide range of operating parameters and the ability to control power output with greater accuracy. Its superior thermal performance, combined with its high frequency switching capability, make it an ideal choice for a wide range of applications, from electric motors to LED lighting.
