FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, in particular to a device for collection of electrical energy and to an energy generator containing such a device. Proposed device (3) for collection of electrical energy contains rectifier module (9) and control device (10). Rectifier module (9) contains the first charging circuit for collection of energy at positive voltage of energy collector (2) and the second charging circuit for collection of energy at negative voltage of energy collector (2). The mentioned charging circuits contain common coil (L) and common electronic switch (13). In addition, each of these charging circuits contains capacitor (Cp, Cn) and shut-off element (Dp, Dn). Charging circuits use coil (L) together, so device (3) has a simple circuit solution and a compact design. In addition, energy is collected efficiently due to the single-stage conversion of alternating voltage to constant voltage and a function of tracking a point of maximum power of control device (10).
EFFECT: creation of a simple and compact device for provision of electrical energy collection from extremely low-voltage (in millivolt range) sources.
