Customer ServiceMoreover, the transformer performed at a maximum efficiency of 98.67%, with a decrease of 3.33 °C in the overall temperature of the transformer as compared to the transformer without air gaps. 1. Introduction
The experimental results showed that the proposed HFT achieved a balanced flux density and magnetizing inductance with a high power density and low cost. Moreover, the transformer performed at a maximum efficiency of 98.67%, with a decrease of 3.33 °C in the overall temperature of the transformer as compared to the transformer without air gaps.
These integrated modules have an integrated transformer, which is switching at a very high frequency range of 11MHz to 15MHz. Using an integrated transformer module eliminates the need of external transformers, which results in a reduction in size and height of the overall system.
Figure 22 shows that the highest recorded temperature of the 3P-HFT was approximately 64.6 °C at a steady state point. The temperature distribution among the core limbs of the transformer was seen to be even because of the distribution of inside the transformer limb, which resulted in similar core losses within the core limbs.
(1) Depends on the variant of the device. High-voltage isolated bias power supply circuits have an HV battery as a power source in HEV and EV. As an HV battery, 400V and 800V voltage batteries are the most common in HEVs and EVs. The isolated bias supply connected to the HV battery needs to support a wider input voltage range.
Although, LV batteries are common as a power source for isolated bias power supplies, often both LV and HV batteries are used to provide redundancy in the system. A redundant power supply can lead to achieve higher functional safety of overall system. Figure 1-1 shows a traction inverter block diagram. Figure 1-1. Traction Inverter Block Diagram
