This paper presents a soft-start circuit using the pulse width-modulation (PWM) method. The motor is controlled by the dc chopper associated with a low-cost PWM chip TL494. The design criteria are ...

The LLC converter-based dc transformer is popular for its stiff voltage gain, very high efficiency, and simple control. To avoid excessive start-up inrush current and hardware overdesign, the ...

Designed for efficient, and low-cost power supplies for applications up to 8W, including lighting, smart-home equipment, ...
