A push-pull type self-oscillating power converter uses a main power transformer T1 connected to a current transformer T2 in series in such a way that a secondary current flowing through secondary sides NS1, NS2, NC1, NC2 of the two transformers is feedback to the primary side NE1, NE2 of the current drive transformer to generate a drive current for driving two switches Q1, Q2. The drive current is proportional to the secondary current in the secondary side of the main power transformer. |
