Self-oscillating switching power supply with output voltage regulated from the primary side |
摘要 |
Regulation of the output voltage of a power supply employing a flyback-type self-oscillating DC-DC converter employing a transformer is implemented in the circuit of the primary winding of the transformer by realizing a current recirculation loop for discharging the energy cyclically stored in an auxiliary winding of the self-oscillation loop of the converter such as to represent a replica of the circuit of the secondary winding of the tranformer and by summing a signal representative of the level of the energy stored in the auxiliary winding with a drive signal on a control node of a driver of the power switch of the converter. <IMAGE> |
