Abstract

A high frequency matrix transformer power converter module includes a dedicated, pre-wired secondary winding, inductor and filter capacitor wherein the electrical conductor forming the dedicated secondary winding is made from a flat ribbon material and passes through adjacent cores forming the interdependent magnetic elements of the matrix transformer such that helical portions of the conductor forming the winding are in complementary arrangement within the core structure and provide an opening through which a second electrical conductor forming a primary winding may be inserted after the module is constructed to obtain the desired transformation characteristics. A number of modules may be arranged side-by-side to provide a higher power output wherein the output voltage busses of the modules are connected together and wherein through holes of each module are in registry to permit wiring of an undedicated primary winding to obtain the desired power output.

Dependent claims

Matrix transformer converter module for use in a high frequency power converter, said module comprising,

at least one interdependent magnetic element defining a matrix transformer section;
means in each of said at least one interdependent magnetic elements defining at least one winding comprising an electrical conductor and having first and second ends, said at least one winding passing at least once through each of said at least one interdependent magnetic elements defining said matrix transformer section:
said means defining said at least one winding further means defining a passage for receiving a second electrical conductor having first and second ends to form at least one second winding:
inductor circuit means having two terminals, one of which terminals is coupled to said at least one winding and the other of which terminal is coupled to a output terminal defining a first voltage distribution bus whereby said inductor circuit means is in series between said at least one winding and said output terminal, and
a second voltage distribution bus, said first and second distribution busses being physically and electrically separated from one another whereby a voltage potential is developed between said busses when an electrical conductor carrying an excitation signal is present to form said second winding.
