When need larger output power, generally adopt the double normal shock type conversion circuit of voltage overlay, as shown. Circuit features: (1) two normal shock type conversion circuit in parallel, T1 and T2 inverting 180 o drive, a doubling of the power and output frequency doubled, ripple and dynamic response is improved; (2) the series S1, S2, S3, S4 series), switch tube pressure by half; (3) to cancel the feedback coil, V1, V2, VpV4 are can feed path, reduce the production technology of transformer and other requirements; (4) with dead zone limit, features two parts there is no common mode circuit conduction problem, and high reliability. Characteristic: normal shock: conduction type feeder to load, when the time L power supply to the load. Pressure: single pipe is excited, maximum voltage switch tube is 2 uin. Two pipe is shock: switch tube maximum voltage for Uin. : transformer utilization rate is not high (only using the first quadrant hysteresis loop), the production process to add on the feed can coil. Purpose: because the two pipe is shock parallel circuit has big output power, output pulse frequency doubling, easy to filter, switch tube pressure by half (about the input voltage Ui. , so widely used in high power conversion circuit, is considered to be high reliability at present, manufacturing is not the main circuit of a complex.
