LLC series resonant topologies has many unique characteristics and improvements over PWM topologies. However, at light load or open load, the unstable output voltage is one of critical issues of LLC-SRC which uses diodes as rectifiers. The traditional solution employs dummy load, nevertheless it results in high dummy load loss and low system efficiency. This paper analyzed the root cause that result in the open load issue and proposed a simple and practical solution, which can stabilize the… CONTINUE READING
