First Claim
1. A DC to AC conversion circuit, comprising:
- an inverter having two input contact points and two output contact points, the two input contact points receiving a DC signal, and the two output contact points outputting an AC signal;
a first inductor having a first terminal and a second terminal, and the first terminal of the first inductor coupled to one of the two output contact points of the inverter;
a first capacitor having a first terminal and a second terminal, the first terminal of the first capacitor coupled to the first terminal of the first inductor, and the second terminal of the first capacitor coupled to the second terminal of the first inductor;
a second capacitor having a first terminal and a second terminal, the first terminal of the second capacitor coupled to the second terminal of the first inductor, and the second terminal of the second capacitor coupled to another one of the two output contact points of the inverter and a load; and
a second inductor having a first terminal and a second terminal, the first terminal of the second inductor coupled to the first terminal of the second capacitor, and the second terminal of the second inductor coupled to the load;
wherein the AC signal is outputted to the first inductor and the first capacitor so as to store energy and to charge the second capacitor with the stored energy, and the inverter inverts a polarity of a voltage across the first capacitor by using a soft switching operation so as to transmit the stored energy to the load.

Abstract
A DC to AC conversion circuit including an inverter, a first inductor, a first capacitor, a second inductor and a second capacitor is provided. The inverter has two input contact points and two output contact points. The input contact points receive a DC signal, and the output contact points output an AC signal. The first terminal of the first inductor is coupled to one of the two output contact points. The first capacitor is coupled to the first inductor in parallel. The first terminal of the second capacitor is coupled to the second terminal of the first inductor, and the second terminal of the second capacitor is coupled to another one of two output contact points. The first terminal of the second inductor is coupled to the first terminal of the second capacitor, and the second terminal of the second inductor is coupled to a load.
