Patent TW-I762396-B (TW)
Inventor: CHEN SHIN JU
IPC: H02M3/10
Filed: 2021-08-02
Granted: 2022-04-21
Abstract: This invention relates to a high voltage conversion ratio DC-DC converter, which consists of two sets of step-up converters connected in series with parallel input and output, and the voltage lift module is connected in series with the output side to enhance the voltage gain; the voltage lift module consists of two coupling inductors connected in series with two lift capacitors and lift diodes on the secondary side, and the two power switches are operated in a staggered manner with half switching period difference, so that the current ripple of the primary winding of the coupling inductors can be partially eliminated to reduce the input current ripple size. Thus, with high boost characteristics, but without operating at very large on-ratios, the power switch has a low voltage stress far below the output voltage at high output voltages, which reduces the conduction loss of the power switch. When high input current is applied, it has low input current ripple, and the leakage inductance can improve the reverse recovery loss of the diode, making it suitable for high boost, high efficiency and high power applications, and increasing the practical efficiency characteristics in its overall implementation.
