Latest Patents

Chih Chi Chang's latest patents include an "Active clamp flyback converter capable of switching operation modes." This invention features a power converter that utilizes an active-clamp flyback topology, incorporating a low-side switch, a high-side switch, and a control circuit. The low-side switch connects a primary winding of a transformer to an input ground line, while the high-side switch is connected in series with a capacitor to form an active-clamp circuit in parallel with the primary winding. The control circuit provides signals to the switches based on a current-sense signal and a compensation signal, allowing the converter to operate in complementary and non-complementary modes.

Another notable patent is "Active clamp flyback converters and control methods thereof." This control method for a power converter also employs an active-clamp flyback topology. It generates consecutive switching cycles, including modified and normal flyback cycles, ensuring that the high-side switch is turned OFF during the normal flyback cycle. The high-side switch is activated after a blanking time during the modified flyback cycle, enabling zero-voltage switching for the low-side switch.
