In fact, for street lamps, higher efficiency and longer life are indispensable to reduce costs.
The switching power supply designed for LED lights must also be efficient and durable to ensure that it has the same maintenance-free life as LED lights.
Resonant converters are one of the most popular power topologies here because their performance leads to higher power efficiency and reduced EMI than previous power topologies.
Soft switching is an important feature of resonant converter.
However, the use of parasitic diodes (bodydiode) in resonant converters sometimes leads to system failure.
The charge stored in the parasitic diode must be completely removed to avoid large current and voltage surges, including high dv/dt and high di/dt in the topology.
Therefore, the key parameters of the power MOSFET, such as Qrr and reverse recovery dv/dt, will directly affect the dynamic performance of the resonant converter.
