“…Although the method claims limited extra circuitry components or volume/weight required to depress the switching noise, its performance will be seriously impaired due to the inevitable leakage inductance accompanying the additionally coupled winding, which is not accounted for in the theory. Another paper [2] proposed a different improved compensation circuit to reduce the effect of leakage inductance. In this external circuit, the compensation capacitor is connected to both sides of the extra coupled inductor, and the effect of leakage inductance will be greatly reduced.…”

“…However, this itself is a difficult task. Many researchers endeavor to construct inductor parasitic capacitance models and several parameter assignments have been proposed [1][2][3], even though the thickness, pitch or tightness deviation of the winding under realistic industrial mass production will affect the parasitic capacitance. Neither way is appropriate to reliably compensate for all the products under mass production.…”

A Bilateral Zero-Voltage Switching Bidirectional DC-DC Converter with Low Switching Noise

This paper proposes a novel bilateral zero-voltage switching (ZVS) bidirectional converter with synchronous rectification. By controlling the direction and timing of excessive current injection, the main power switches can achieve bilateral ZVS under various loads and output voltages. Compared with the common soft-switching power converter with only zero-voltage turn-on, the proposed bilateral ZVS bidirectional converter can achieve both zero-voltage switching on and off in every switching cycle. This feature can alleviate the output switching noise due to the controlled rising and falling slope of the switch voltage. Furthermore, the voltage slopes almost remain unchanged over a wide range of output voltages and load levels. The most important feature of bilateral ZVS is to reduce the output switching noise. Experimental results based on a 1 kW prototype are presented to demonstrate the performance of the proposed converter. From experimental results on the proposed scheme, the switching noise reduction is about 75%.
