TDK-Lambda UK has been granted a UK patent for its Zero Voltage Switching Converter (ZVSC) by the UK patent office.In essence, the ZVSC topology uses a half-bridge switching circuit with additional noise cancelling circuitry to reduce conducted common-mode noise. Since noise is reduced, a much smaller EMC filter is needed for the power supply to comply with EMC regulations, thus achieving a compact, high power density unit. TDK-Lambda's NV300 uses such a topology, achieving a power density of 8.3W/in3.
