Abstract:
A circuit includes a transformer configured with a primary winding and a secondary winding that are driven from a voltage supplied by a thermoelectric generator (TEG). The circuit includes a bipolar startup stage (BSS) coupled to the transformer to generate an intermediate voltage. The BSS includes a first transistor device coupled in series with the primary winding of the transformer to form an oscillator circuit with an inductance of the secondary winding when the voltage supplied by the TEG is positive. A second transistor device coupled to the secondary winding of the transformer enables the oscillator circuit to oscillate when the voltage supplied by the TEG is negative. After startup, a flyback converter stage can be enabled from the intermediate voltage to generate a boosted regulated output voltage.

Claim (Index 17):
An apparatus comprising:\n a voltage supply terminal configured to receive a supply voltage; a transformer having a primary winding including a first end coupled to the voltage supply terminal, and a secondary winding including a second end coupled to the voltage supply terminal; a startup stage circuit coupled to a third end of the primary winding and a fourth end of the secondary winding, and configured to generate an intermediate voltage greater than the supply voltage; a ring oscillator circuit configured to generate an intermediate switching signal based on the intermediate voltage; and a converter stage circuit configured to generate an output voltage, the converter stage circuit having:\n a first transistor controlled by the intermediate switching signal and configured to excite the primary winding before the output voltage is regulated to reach a predetermined threshold; and \n a second transistor configured to excite the primary winding when the output voltage is regulated above the predetermined threshold.
