Title:
SERVO DRIVE SWITCH POWER SUPPLY AND SERVO DRIVE
Document Type and Number:
WIPO Patent Application WO/2019/056178
Kind Code:
A1
Abstract:
The present invention discloses a servo drive switch power supply and a servo drive. The switch power supply comprises: an input rectifying and filtering circuit, an integrated monolithic power circuit, a primary transformer winding, a self-feeding circuit, a self-feeding winding, a secondary side winding set, and a secondary side output circuit set. The secondary side output circuit set comprises at least one secondary side output circuit. The secondary side winding set comprises at least one secondary side winding. The at least one secondary side winding is coupled with the primary transformer winding and the self-feeding winding, and the at least one secondary side output circuit and the at least one secondary side winding are respectively and correspondingly connected. The input rectifying and filtering circuit is coupled with one end of the primary transformer winding, and the other end of the primary transformer winding is coupled with the integrated monolithic power circuit. The self-feeding circuit is coupled with the self-feeding winding and the integrated monolithic power circuit. The switch power supply provides servo drivers with a plurality of DC power supplies of different voltage levels with better regulating rates while also reducing electromagnetic interference.
