Web10 May 2024 · SMPS stands for Switched Mode Power Supply. It is an electronic gadget or module that comprises a combination of inductors, capacitors and semiconductor gadgets like diodes and MOSFETs. It is utilized to change over a specific DC voltage to another DC voltage level. It is utilized rather than straight or ohmic converters since of higher efficiency. Web13 May 2010 · Mosfet: 2SK2700. The PWM controller receives power from an external power supply. Circuit schematic and signal captures from the circuit are attached. In the signal captures the yellow line is the switching from the PWM controller, blue line is the drain-source voltage @ 0 V AC and 10 V AC. Any pointers are welcome.
