Fig. 7 is a circuit diagram showing an embodiment of a switching device in a heating circuit provided by the present invention. As shown in Fig. 7, the first switching device 10 and/or the second switching device 20 may include a switch ΚΙ 1 and a fifth unidirectional semiconductor element D11 connected in anti-parallel with the switch ΚΙ 1. The switch control module 1 is electrically connected to the switch Π1 for controlling the on and off of the control switch K11. 10014316# single number A0101 page 11 / 21 page 1013098649-0 201233000 first switch device 10 The forward branch is turned on and off. The turn-on and turn-off control of the switch K11 can be performed in the grid section shown in FIG. 2 'FIG. 4 and FIG. 6'. The switch control module 1 can be passed through the first switching device 10 Or when the current of the second switching device 20 crosses zero or after the current crosses zero, the first switching device 10 and the second switching device 2 are controlled to perform switching state switching. The heating circuit provided by the present invention has the following advantages: (1) Since the charge and discharge direction of the second charge and discharge circuit is opposite to the charge and discharge direction of the first charge and discharge circuit in terms of the charge memory element, the electric energy can be An alternating reciprocating flow between the battery E1 'charge memory element and the second battery E2, whereby the generated current can cause the first damping element R1 and the second damping element R2 to generate heat, thereby pairing the first battery E1 and the second battery E2 is heated to achieve alternating heating of the first battery E1 and the second battery E2, and the heating efficiency is high. (2) Flowing through the first battery Ei and the second battery E2 and the first switching device 1 and the second switching device 2 due to the current limiting action of the current memory element and forming only a single charge and discharge circuit per time period The configuration of the smaller 'other' charge and discharge circuit and the presence of the first current memory element L1 and the first current memory element L2 can further restrict the flow through the first battery E1 and the second battery E2 and the first switching device 1 And the current of the second switching device 20, thereby avoiding the large current damaging the battery and the switching device 〇(3), when using the unidirectional current limiting, increasing the discharge efficiency of the first battery ei and the second battery E2 while reversing The charging current is limited to avoid damaging the first battery E1 and the second battery E2, thereby ensuring that the thermal efficiency is increased while not damaging the first battery and the second battery E2 and the switching device. #单编号A0101 Page 12 of 21 1013098649-0
