Title:
ENERGY SAVING CIRCUIT AND STARTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/151385
Kind Code:
A1
Abstract:
An energy saving circuit and a starting device. Control switches (K) and loads (RY) for which energy saving is required constitute a first series circuit. The first series circuit is connected to a first power supply (PA). A first switch (S1), the control switches (K), and the loads (RY) constitute a second series circuit. The second series circuit is connected to a second power supply (PB). The voltage of the first power supply (PA) is less than that of the second power supply (PB). When the control switches (K) are turned off, the first switch (S1) is turned on, and the second power supply (PB) drives the loads, and then the first power supply (PA) maintains supplying power to the loads (RY). The number of control switches (K) and loads (TY) is at least two.
