Ac-Dc Conversion TRIZ Cases

An inrush current controller regulates pulse width modulation signals to manage charge pump voltage generation.

Segmenting battery modules into independent converters eliminates circulating current loss and isolates thermal runaways in centralized energy storage systems.

Delay devices adjust voltage command transmission times to prevent cross-current damage and reduce power converter capacity.

Individual power converters control separate fuel cell stacks, resolving SISO instability and preventing shutdowns from single stack failures.

Master-slave UPS coordination synchronizes inverter output currents, resolving instability and high costs in parallel power distribution.

Wireless synchronization signals correct phase shifts among parallel inverters, reducing power loss while maintaining system adaptability.

A suspension arrangement uses a coupling device to allow relative rotation between the support member and structure.

A ferromagnetic attenuation element magnetically couples to power converter conductors to induce eddy currents that dampen electrical ringing.

Segmented intermediate circuits prevent circulating currents in energy supply networks while enabling efficient multilevel voltage generation.

A driving circuit selects turn-off parameters adaptively to optimize switching speed and reduce energy loss.

A bypass circuit supplies self-feeding drive power from adjacent cell converters within a modular multilevel converter block.

An isolated power supply circuit merges separate power sources into one unit, reducing system volume while maintaining reference ground isolation.
