DC/DC converter using a transformer to galvanically insulate the load from the primary power supply source, to ensure said insulation even along the feedback path, thanks to a charge-transfer network inserted along said path. Said network consists essentially of two capacitors (C1) and (C2) and two pairs of synchronous electronic switches (IC1) and (IC2) provided with MOSFETs. The pair IC1 when closed connects C1 in parallel with the load Ro, while IC2 when closed connects C1 in parallel with C2, which has one end connected to the primary ground. The pairs IC1 and IC2 are controlled by two respective periodic signals, which are mutually decoupled through the transformer and correspond to the signals used for switching the two power transistors of the converter in push-pull configuration. |
