For street lamps, higher efficiency and longer life are indispensable for cost reduction.Designed for the LED power supply switch power supply, also must have a high efficiency and durability, to ensure that it has as long as the LED life without maintenance.Here, the resonant converter is one of the most popular power supply topology, this is because compared with previous power supply topology, their performance has brought higher power efficiency, and can reduce EMI.Soft switch is an important characteristic of resonant converter.But the resonant converter used in parasitic diodes (bodydiode) can sometimes lead to system failure.Stored in the parasitic diodes charge must be clear, to avoid large current and voltage surge, including topology structure of high dv/dt and di/dt.
