Abstract

An effective output voltage regulation method using harmonic burst control is presented. This method can greatly improve operating performance of the full-bridge series-resonant dc-dc converter (SRC) applied to electric vehicle (EV) battery charging. The proposed harmonic burst control not only provides load regulation, but it also achieves soft switching at both turn-ons and turn-offs under all load conditions. As a result, it improves the system efficiency over 10% for light-load conditions without any extra hardware, compared to that of the traditional frequency modulation method. Moreover, it has much smaller pulsed power over a wide range load compared to the traditional bang-bang burst control. Theoretical analysis of the series-resonant circuit and power loss analysis are discussed in detail in this paper. Experimental results based on a 1-kW prototype with 20-cm air gap between the primary and secondary sides of the series-resonant converter are presented to demonstrate the effectiveness of the proposed control strategy.

Abstract

In this paper the Z-source converter is introduced to power factor correction (PFC) applications. The concept is demonstrated through a wireless power transfer (WPT) system for electric vehicle battery charging, namely Z-source resonant converter (ZSRC). Due to the Z-source network (ZSN), the ZSRC inherently performs PFC and regulate the system output voltage simultaneously, without adding extra semiconductor devices and control circuitry to the conventional WPT system such as conventional PFC converters do. In other words, the ZSN can be categorized as a family of the single stage PFC converters. In addition, the ZSN is suitable for high power applications since it is immune to shoot-through states, which increases reliability and adds a boost feature to the system. The ZSRC-based WPT system operating principle is described and analyzed in this paper. Simulations, and experimental results based on a 1-kW prototype with 20-cm air gap between the system primary and secondary side are presented to validate the analysis, and demonstrate the effectiveness of the ZSN in the PFC of the WPT system.
